    Introduction: backscattered bodies

    In 2005 the UK Home Office and the US Transportation Security Administration

    (TSA) began trials of new X-ray devices for the screening of bodies at border check-

    points. Rapiscan System's Backscatter scanners appeared in terminal 4 of London'sHeathrow airport and in Phoenix's Sky Harbor airport, producing screened images of

    passenger's bodies as they passed through security checkpoints. In the TSA's budget

    statement to Congress in 2007, special mention was made of the substantial investment

    in `whole body imaging' or `backscatter X-ray', with a statement that ``the technology

    produces an image to identify contraband secreted on an individual without subject-

    ing them to an invasive inspection'' (TSA, 2007). In October 2008 the TSA

    announced the expansion of body scanning at US airports (TSA, 2008), and in the

    same month the European Commission moved to allow for the widespread introduc-

    tion of similar scanners in airports across the EU by 2010 (European Digital Rights,2008). Ultimately proposed, then, for use in major airports across Europe and the US, as

    well as in the London Underground system in the form of millimetre-wave technology

    Abstract. The UK Home Office and the US Transportation Security Administration have madesubstantial recent investment in new Backscatter X-ray scanners to screen bodies at securitisedborder checkpoints. Promising to make the invisible visualisable, these devices project an image ofa naked body onto a screen to identify concealed `risk'. Contemporary security practices which seekto fix identity at the border through biometrics, datamining, and profilingof which the `whole bodyscanner' is parthave their genealogy in efforts in aesthetics and medical science to mine the body forcertainties and reveal something of the unknown future. The scan is revealed as a simultaneouspartitioning and projection, the body `digitally dissected' into its component parts, from which aspecific, securitised visualisation is shaped. Drawing on the entangled histories of `body knowledge'in art, science, and anatomytheir techniques of abstraction and technologies of visualisationwe

    explore what light may be shed on the Backscatter scan and, more importantly, what ramificationsthis may have for a critical response. Challenges to the biometric border have tended to centre onsurveillance, making appeals to privacy and bodily integrity. However, if border disclosures which`take apart' the body are more precisely understood as visualisations, then there are more fundamentalissues than recourse to rights of privacy can counteract.

    (The Times 2005, page 4), Backscatter scanners hold out the promise of imaging the

    unseen, penetrating the surface, and making visible that which is hidden from view,

    opening up new visualisations of the unknown, potentially risky body, as well as newperspectives on its management.

    Backscatter scanners utilise `Compton scattering', a phenomenon by which the

    momentum and wavelength of x-rays change when coming into contact with matter,

    with lower energy rays recoiling from a surface or scatter point. Named after its

    discoverer, Arthur Compton (who won a Nobel Prize in 1927 for his achievements),

    Compton scattering was a key milestone in 20th-century physics, helping to establish

    the particle nature of electromagnetic radiation (Nobel Lectures, 1965). In the Back-

    scatter scanner, the low-energy, excess, `scattered' radiation is harnessed to produce an

    image of a person on a screen. In contrast to medical X-rays, the Backscatter does notpenetrate the skin, but `sees through' layers of clothing, distinguishing organic from

    inorganic matter to display a naked form onto a screen, to be viewed by the scanning

    operative (see figures 1 and 2). The outline of body parts, body hair, and genitalia is

    clearly visible on the screen shown in the TSA's promotional video alongside a

    concealed ceramic knife and detonator.(1)

    In contemporary security practice, Backscatter is but one illustration of the drive to

    ``visibilize the invisible'' (Stafford, 1993, page 17), as the historians of art and the body

    put the problem, to probe beneath what is immediately available to an observer's

    senses. Far from the promised `whole body image', the Backscatter scan is actually a

    composite of dissected elements of a body, pixelated by X-rays which are ``received by

    high resolution detectors and passed to advanced image processing software''

    (Rapiscan Systems, 2006), then reassembled. The resulting image resembles a shadowy

    negative imprint of body contours (see figure 3) which can then be abstracted into what

    the TSA refer to as `chalk lines', reminiscent of those at a crime scene. The imageviewed by the screening operative at the border checkpoint, then, is not a copy',

    but an abstraction and a recomposition of the dimensions and densities of the body.

    Broken apart in this way, the unknown `threat' is made knowable and amenable

    to intervention: freight vehicles are X-rayed at ports for the (live or dead) bodies of

    illegal immigrants; cargo container shipments are screened for explosives; subway

    passengers for concealed improvised explosive devices; young children are imaged bymillimetre-wave technology at Amsterdam's Schipol airport. Yet, this quest to make

    the concealed interiors and surfaces of the body known to the `outside' is not at all

    novel: it is, in fact, an intrinsic part of the conjoined histories of visualisations of the

    body in fine arts and the medical sciences. The genealogies of body knowledge reveal

    precisely an imaging and imagining of the body via excavation of its component parts.

    In the medical sciences, as well as in the arts, where anatomical knowledge has

    influenced what has appeared in the field of vision, knowledge of the human body

    dissected, dismembered, displayed for expert viewing has been thought to reveal

    something of the human soul itself, making the most intimate aspects of human lifeand motivation transparent.

    If we are to understand the implications of the embracing, in contemporary

    security practice, of the possibility of absolute identifiability via the body, whether by

    biometrics, body scans, or by forensic approaches to personal data, we cannot ignore

    the complex histories of taking apart bodies and subjects in order to see them and to

    know them. As art historian Jonathan Crary (1992; 2001) has argued, the way that we

    pay attention to particular bodies, objects, or phenomena is not self-evident, but is

    specific to situated practices of observation. Crary locates a critical historical moment

    in the 19th century, when perception was relocated ` in the thickness of the humanbody'', thereby making it amenable to management, and offering human vision as ``a

    component of machinic arrangements'' (2001, page 13). Certainly, the relation between

    human bodies and human vision, and the machinic arrangements for their visualisation

    and deployment, has become critical to current manifestations of border controls.

    Thus, the biometrics of iris scans, for example, have become an assumed identity

    `anchor' in the human body, and a prerequisite for fast-track security. Rapiscan X-ray

    booths placed alongside Heathrow's terminal 4 fast-track `MiSense' iris scanners

    are similarly predicated on the mapping of digitally partitioned images of body parts as

    part of a drive to ``fix people's identities'' as the Home Office paper ``Securing the UKBorder'' puts it (Home Office, 2007, paragraph 1.4). It is precisely the fraught nature of

    the penetrating disclosures that are required at the border in the name of security that

    forms the focus of our discussion in this paper.

    Public concerns about the implementation of Backscatter have revolved around the

    `privacy risks' involved.(2) The USA's Electronic Privacy Information Center (EPIC,

    2005) argues that Backscatter scans are ``equivalent to a `virtual strip search' for all air

    travellers'', and that the machines show ``extraordinary disregard for the privacy rights''

    of passengers. Because privacy has occupied the primary political ground, debates

    about body visualisations at the border have centred on the distanciation of theobserver and observed: screeners and their monitors are placed in booths or adjacent

    buildings so they see only the digital simulacra and not ` the identity of the real

    person''; `cloaking' technology is used so that images of some body parts are `screened

    out'; and images are anonymised until a `risk' is identified (New York Times 2005).

    (2) Currently, the TSA proposes the Backscatter scan as a voluntary alternative to a `pat down'search for those who have been selected for secondary screening. However, the American CivilLiberties Union claims that the scanner will, in fact, be used as a primary search for randomselectees and people flagged by watchlists, and it questions the continuing `voluntary' basis of thescan (ACLU, 2008). In Schipol, Heathrow, and Luton airports, body screening is being framed as aquicker and more convenient alternative to queuing for traditional security checks. The EuropeanCommission has insisted that body screening will remain voluntary, but the European Parliamenthas raised concerns that the Commission's plans will introduce significant new norms into airportsecurity procedures, and have called for greater consultation (The Times 2008).

    As the image of the `potentially risky' body is abstracted from the person whether

    this is by prescreened images of an iris or face, or by the screening of `whole bodies'

    so, simultaneously, other visualisations of the person are deployed, from multipleand fragmented databased information. Long before a physical boundary is reached,

    forensic data mining dissects an individual's behaviours and associations apparently

    identifying `hidden intent' and `suspicious behaviour' (Amoore and de Goede, 2005;

    Ericson, 2007; Sparke, 2005). It is the people identified for secondary searches,

    primarily through the projections that are produced from the fragments of their data,

    who are considered worthy of a closer look' and are singled out for Rapiscan screening.

    The drive of Backscatter to know the fleshy body by breaking down and reassembling

    its mass collapses into the broader visualisation of the subject at the border via forensic

    approaches to personal data.In this paper we make a case for understanding techniques such as Backscatter

    through the genealogies of visualising that which is `out of sight' in aesthetic and

    medical science practices. Motivated by a concern to highlight, in the burgeoning

    literatures on biometrics, the almost complete absence of reflection on the metric of

    the bio that is at work, we focus on situated histories of knowledge. First, we trace

    other historical moments when the body has become a locus of anxiety and a domain

    to be mined for certainties. Renaissance and Enlightenment anatomical dissections

    fostered a form of knowledge that sought to know by reducing a body to its component

    parts. Second, we turn to the technologies of visualisation that record and project thebody. Drawing on the intertwined literatures of art history and history of science, we

    ask how it becomes possible to visualise bodies in particular ways. What is thought to

    be gained or revealed from an intimate knowledge of abstracted parts of a corporeal

    whole? At the heart of our arguments is the observation that dissection and visualising,

    partition and imaging, are inextricable aspects of the same process, a process through

    which knowledge of some `whole' (body, individual) is thought possible. In what follows,

    though we differentiate our discussion of dissection from visualisation for analytical

    clarity, it is precisely the conjoined nature of the practices of taking apart and making

    visible that we emphasise.In the final section we reflect on the critical response to the implications of

    contemporary forms of body knowledge. Much of the critique of contemporary bio-

    metric screening at borders has centred on power as surveillance ``the garnering of

    personal data for detailed analysis'' as David Lyon (2003, page 1) puts it and it is the

    appeal to privacy that has dominated the politics of response. We suggest that border

    disclosures which `take apart' the body exceed surveillance and signal more precisely a

    visualisation or a particular visual knowledge of the body and subject. A critical

    response to the digitised dissection of bodies at borders which highlights its discrim-

    inatory potential, and which makes recourse to rights to privacy, rightly targets itsdeleterious potential effects, but threatens to leave its tendencies and assumptions

    intact. Just as the 18th-century physiognomists saw the workings of the human body

    to be secondary to a deeper knowledge of human essence and soul, so the contempo-

    rary security drive for body knowledge is motivated only superficially by the search

    for concealed weapons or contraband, and more profoundly by a desire to pierce

    the coverings of dress, status, or feigned identity in order to reveal something of the

    unknown future hidden within.

    Partitioning the worldBackscatter, then, involves the systematic reduction of the body into its identifying

    traces, from which new composite projections can be made a form of what we term

    `digitised dissection'. Historically, dissection has made knowledge of the body and its

    interiority possible, implying a neutral practice of partitioning for inspection, but also

    the violent dismemberment of flesh. Jonathan Sawday (1995) traces a burgeoning

    fascination with anatomy to the European Renaissance, when writers, thinkers, andartists became entangled in what he calls a `culture of dissection'. Artistic' and `medical'

    visualisations of the body were inseparable in 16th-century centres of Renaissance

    learning: anatomy was a required subject for artists, and lifelike wax and wooden

    sculptures of dissected bodies were displayed to the public (Benthien, 2002, page 45).

    Dissections in this era were important public events, sometimes lasting days, and the

    motifs of anatomy and flaying featured frequently in art, theatre, literature, and popular

    culture.

    This `culture of dissection' contained the beginnings of what would later become

    scientific rational enquiry, a particular way of understanding the world. Yet it also heldwithin it a dark enthralment with bodily surfaces, depths, and interiors which later

    claims to objectivity and learning (with the 17th-century triumph of `science' in its

    modern sense) could not fully mask (Sawday, 1995, page 5). Illustrations of dissections

    from the 16th century show bodies happily participating in their own dissection, flaying

    their own skin to reveal their bodily interior. This ``willing self-presentation'' (Benthien,

    2002, page 64) has been linked to the Calvinist doctrines of rigorous self-examination

    and exposure (Sawday, 1995, pages 110 ^ 111). This glad participation in disclosure

    mirrors contemporary `confessional' demands within border and visa regimes, where

    travellers are expected to reveal and `flay' their histories, identities, associations, andbodies to knowing expert eyes in the name of `safety' (Salter, 2006, page 181).

    The partitioning of the body in Renaissance anatomy theatres was allied to a

    broader partitioning of the world to gather knowledge: unpeeling the skin to reveal

    somatic secrets was an attempt to divine, demonstrate, and publicly reassert the social

    and moral order (Sawday, 1995, page 75).(3) Celebrated anatomists of the day, such as

    Andreas Vesalius, championed distinct and lasting ways of viewing the body, and also

    the world; removing the skin and naming what lay beneath was a revolutionary new

    way of `seeing' the body as layers and systems (Benthien, 2002, page 45; Cregan, 2007,

    pages 49, 54). Claudia Benthien argues that we still operate with the belief that ``knowl-edge of what is essential means breaking through shells and walls in order to reach the

    core that lies in the innermost depths'' (2002, page 7).

    Bodily dissection and the systems of knowledge it produces are always connected to

    the way in which this knowledge is inscribed. Early dissection practices evolved along-

    side the development of mechanical printing: the body's bloody density had to be made

    intelligible and communicable via conventions of representation that were shaped by

    the flat spatiality of the anatomical atlas, through which knowledge was disseminated

    (Waldby, 2000, page 91). Furthermore, explorations of the body mirrored the con-

    temporary exploration of new territories. In a discussion of anatomy practices inElizabethan England, Kate Cregan (2007, page 49) argues that dissection of the body

    was related to the emerging science of cartography; anatomisation and territorialisation

    were both practices of `unification and disintegration', and the violent, yet creative,

    conquering and mapping of territory was mirrored in the violent and creative abstraction

    and rebordering of the body and its systems within anatomic practices.

    (3) Waldby (2000), Sawday (1995), and Cregan (2007) all note the historical links between medicalknowledge, and penal and sovereign power. Between the 15th century and the 19th centurydissections were traditionally performed on criminals, as extensions of their punishment. Thedemise of this widespread practice is part of the reconfiguration of the relationship between power,punishment, and spectacle described by Foucault (1977). Waldby (2000) notes, however, that therelation of anatomy to penal punishment continues: the subject whose body was frozen, sliced up,and scanned to produce the world's first three-dimensional, `virtual' anatomical `atlas' was aconvicted and executed murderer.

    Taking people apart: digitised dissection and the body at the border 449

  • 7/28/2019 Amoore Hall 2008 Taking People Apart

    7/22

    Anatomy, then, has always been a potentially violent `writing practice' through

    which flesh is disintegrated to extract knowledge and to generate ` reproducible and

    communicable traces''; contemporary digitisation and `virtualisation' of dissection con-tinue this trend by writing flesh as digital code (Waldby, 2000, pages 89, 94). In this

    way, Backscatter is a specific, securitised medium through which flesh is made com-

    prehensible, reforming a digitised whole from residue, recomposing a sense of solidity

    from calibrations of planes, crevices, and boundaries. This process retains partition

    and extraction at its core. In an age of bytes, pixels, and codes, dissection remains an

    inherently violent practice of translation that knows by `tearing apart' (Stafford, 1993,

    page 38).

    If the Renaissance response to bodily interiors was one of awe at the mapping of

    an unknown territory, then the confident burgeoning rationalist paradigms of 18th-century Enlightenment art and science understood dissection more broadly as a paradigm

    ``for any forced, artful, contrived, and violent study of depths'' (Stafford, 1993, page 47).

    As `life' became the object of epistemological conquest in models of science and

    governance within biopolitics (Foucault, 2000, page 73), the body came to be imagined

    as a machine. This distinctly modern ``anatomical body'' (van der Ploeg, 2003, page 65)

    in turn became the subject of an intense and studied calibration and measurement

    (Sawday, 1995, page 32). Dissection was now not only a surgical probing, but a

    ``searching operation performed on a recalcitrant substance'', capturing perfectly the

    Enlightenment preoccupation with ``decoding, dividing, separating, analysing, fathom-ing'' bodies, beliefs, and ideas in order to attack ``the duplicity of the world'' (Stafford,

    1993, page 47). All deceptive appearances could be brought to truth under methodical

    and meticulous analysis.

    Mathematical certainties and simplicity were sought in all areas of social, moral,

    artistic, and cultural life (Stafford, 1991, page 468), and the yearning for quantification

    and standardisation created new possibilities for calibrations of human physicality,

    behaviour, and interaction. It was an era obsessed by ` stripping away of excess by

    decomposition and fragmentation for the purposes of control'' (Stafford, 1993, page 47).

    More than anything else, it seems to have been a ` human yearning for rigidity'' and the``longing for hard lines and clear concepts'' (Douglas, 1966, page 162) which absorbed

    Enlightenment rationalists in their endeavours to divide, classify, and categorise the

    world, its anomalies and regularities (Daston and Park, 1998; Park and Daston, 1981).

    These endeavours were bound up in an effort to secure a social and moral order.

    The era's ``fearful disdain of mixtures'' (Stafford, 1993, page 211) was the very product

    of the burgeoning ``habit of purity'' (Bowker and Leigh Star, 1999, page 300). It is, after

    all, in efforts to order the world that the anomaly the barbaric, the monstrous, the

    `incorrect' takes shape and gains meaning.

    Anatomy now sought to ` simplify, abstract, isolate and detach segments of thebody in order to calculate incongruity'' (Stafford, 1991, page 116), leading to new

    taxonomies and interpretations of the human body. In the 18th-century science of

    physiognomy, epitomised in the work of Johann Lavater, was found a systematic

    attempt to `read' and categorise character and intent from the calculable features

    of the human anatomy (Stafford, 1993, page 107). This endeavour would be further

    developed in the phrenology of Josef Gall, whereby intellectual capacities could be

    discerned through the shape of the skull (Colbert, 1997, page xi). Stafford (1993, pages

    103, 112) characterises these as `` `sciences' of the contingent'' and demonstrates the way

    in which efforts to locate in the planes of the body and face the `ideal' aestheticmeasurements of national types (evidenced in the late-18th-century anatomical drawings

    of Pierre Camper) soon became entangled with efforts to compare the human body

    and to link anatomy with intelligence.

    8/22

    The flesh `taken apart' by dissection has always been thought to hold the secret

    authority for moral, political, and social order and ways of classifying bodies. Thomas

    Laqueur (1990), for example, shows clearly how Renaissance anatomists were able toextract evidence from dissections to support the prevalent idea that female genitalia

    were inversions of male sex organs: bodily disclosures were made meaningful within

    existing regimes of knowledge. The Renaissance era saw little tendency to organise

    difference according to `race' (Hodgen, 1964); human diversity was largely made mean-

    ingful by delineations of religion and notions of civility (see Traub, 2000). Yet the

    Enlightenment science of anatomy sought more and more to find the hierarchies

    of an expanding empire within the variation of human bodies, and to encode them

    within categorisations of `race'. By the end of the 19th century, comparative anatomy

    had became a distinct discipline, championed by anatomists such as Georges Cuvier(Augstein, 1999, page 61) and the later physical anthropology of James Prichard

    (see Stocking, 1968). By the middle of the 19th century, Robert Knox's racial science

    had gained widespread scientific and popular influence, locating as it did immutable

    difference and biological determinism in the hierarchically ordered ``races of mankind''

    (Stepan, 1982, pages 45 ^ 46). The efforts expended to distinguish and distance the

    ``Other'' within imperial discourse were multiple, forming a discourse of cultural knowl-

    edge through which different bodies were made knowable, as Edward Said (1978; 1993)

    has shown; anatomical knowledge was core to this location of difference.

    Renaissance and Enlightenment dissections and mappings of the body, then, reveala set of violences, tensions, and racial categorisations which may be reconfigured

    within new technological interventions and epistemological frameworks, but which

    are never resolved. The mobilisation of digital dissection within contemporary security

    regimes continues the interplay between the desire for more refined partition and the

    conviction that, if only the somatic secret could be penetrated, certainty would be

    revealed. Sophisticated virtual imaging techniques that do not touch the body appear

    to realise the cultural ideal of full transparency of body and motive, a key ideal

    in security practice. Yet the apparently unmediated images of bodily interiors and

    surfaces flickering across our screens hides the simultaneous partitioning and projec-tion which these images involve; far from being unmediated, these projections

    are reconstitutions, or reintegrations of parts. The abstraction and calculation of the

    body have, as the above history demonstrates, always been concerned with locating

    the `whole' within culturally mediated grids and taxonomies of difference, risk, and

    pathology. Just as the ontology of the informatised body is shifting contemporary

    understandings of physical integrity, personhood, health, and risk (Novas and Rose,

    2000; van der Ploeg, 2003), so it is the intertwining of security practices with new

    understandings of the body no longer machine, or territory, but digitised information

    to be `read'

    that critical challenges must grapple with.The promise to build `anonymity' into technologies such as Rapiscan, in order to

    `protect privacy', does not address the violence involved in uncovering, breaking down,

    and writing the body into digital form. The body does not remain `untainted'

    (van Dijck, 2005, page 8) by being exposed, even if the data collection leaves its

    surfaces intact, and if `data', `body', and `identity' remain separated until risk is flagged

    by the scanners. As the director of EPIC puts the problem:

    ` what is at stake when prosthetic limbs, a prosthetic breast, scars from burns or an

    accident when these are seen? Is this a question of human dignity?'' (4)

    The entanglement of bodily imaging and biometric probing with border security mustadvance with an acknowledgement that there are fundamental tensions involved when

    we gaze upon the body's surface and its partitioned aspects. The `nakedness' produced

    from technological penetrations of bodily coverings at borders uncovers ``the defence-

    less being in its most elemental form'' (Benthien, 2002, page 99). Technologies whichappear to leave the body surfaces intact may reduce the traditional associations with

    violence and spectacle, yet the spectacle simply mutates.

    Contemporary political terror, Allen Feldman (2004, page 347) argues, has a

    dual face: a visual fixation with `vivisectionist' violence evidenced in places like Abu

    Ghraib, combined with a contrasting ` unlimited capacity to technically sanitise the

    violent act''. Victims of this violence are either ` dismembered and somatically opened

    to history'' or else wholly erased, defaced of identity. Feldman reminds us that the

    process of rendering visible and capturing that visibility is never wholly separate

    from the desire to master, or humiliate, or make vulnerable. Backscatter, then, isa form of technological vivisection, a digitised dismembering, through which bodies

    are ``somatically opened'' and subjects erased simultaneously; the person is reduced to

    a transparency, like baggage, evacuated of vitality and materiality (Parks, 2007, page 194).

    Put simply, dissections have always ambivalently combined seduction with revulsion,

    violence with the promise of safety; and these aporia continue to haunt contemporary

    digitised dissections.

    Imaging the unseen

    If knowledge of the body has been assumed to reside inside, in an interior to beexcavated and projected to the outside, then it is visual practices that have made this

    possible. ` How'', asks W J T Mitchell, ` did the visual acquire its status as the sovereign

    sense?'' (2005, page 265). There is little doubt, at least for theorists of visual culture,

    that, despite the inherent tactility of vision, it is visuality that has come to be repre-

    sented as ``the most superior, most reliable'' of the senses (Bal, 2003, page 13). Thus, in

    ``eyewitness accounts'', in diagrammatic records, in the photographs that accompany

    text, it is the visual record that is regarded as objective and dispassionate, embodying

    an `inherent credibility' (Jay, 2002, page 269). Indeed, so potent is the historical

    visualisation of the world that, as James Elkins argues, there is a case for seeing thehistory of the visual as the history of imaging including graphs, charts, maps, nota-

    tions, plans, scientific images of all sorts rather than the history of art per se (2001,

    page 4). Understood in this way, it is not only the images of bodies produced by

    scanning and screening practices that are part of the visual culture of contemporary

    security, but also the risk charts, screened algorithmic calculations, and integrated data

    diagrams that also participate in the visualisation of risky bodies by other means.

    Within a technology such as Backscatter resides a history of taking the body apart,

    but also of imaging the body which extends into multiple techniques of visualisation

    the recomposition of the scattered rays to produce a particular appearance of a solidbody is just one graphical representation among many.

    The dominance of visualisation technologies in knowledges of the body is, at least

    in part, explained by the reification of the visual as a site of dispassionate and

    concentrated observation, apparently the least vulnerable of all sensory artefacts to

    ``subjective intrusion'' (Daston and Galison, 1992, page 82). Citing John Madden's 1958

    Atlas of Technics in Surgery, for example, Peter Galison suggests the elision of surgical

    and artistic anatomical realism: ``Only those operations that were witnessed by the

    medical artist are depicted'' (1998, page 346). Only when the expert eye of an observer

    was present, could the technical procedures of medicine be accurately imaged andrecorded. There is, however, a problematic history associated with the concepts of

    `objective' and expert'. Behind historical drives to develop optical and visualising

    instruments was a preoccupation with removing the subjective interventions of the

    452 L Amoore, A Hall

  • 7/28/2019 Amoore Hall 2008 Taking People Apart

    10/22

    ``meddling, weary observer'' in artistic representations for science (Daston and Galison,

    1992, page 83). The Enlightenment anatomist's proclamation that an unimpeded view

    could uncover the truth was tempered by a mistrust of vision, which became subjectto a ` vehement disproval of sensory ambush, fiction, and untruth'' (Stafford, 1993,

    page 366). The ` congenital sensory frailty'' of humankind (Stafford, 1993, pages 1 ^ 2)

    has required constant amendment by optical machines, instruments, and technol-

    ogies innovations which have proliferated since the 18th century, each promising

    greater clarity and unmediated access.

    The struggle to get at the `hidden' picture encapsulated in Enlightenment visual-

    isation techniques was not considered at the time to be a matter of `objectivity': this

    term only emerged in the 19th century. Rather, a `true' depiction of an object involved

    artistic and scientific intervention by a natural philosopher, ``whose genius vouchsafedthe validity of the move to idealise and correct the unreliable appearance of the given''

    (Galison, 1998, page 328). It was the mechanically produced images of the 19th century

    which brought the idealised notion of an `objective' image, where human interpreta-

    tion was removed by rigorous self-discipline (Galison, 1998, page 329). Later, within

    20th-century scientific discourse, the judgement and interpretative ability of the trained

    expert gained precedence; a specialist's ``practiced'' eye could gaze upon and interpret

    representations to ``perceive patterns where the novice saw nothing'' (Galison, 1998,

    page 337). It is precisely the productiveness of images, and their relationship to the

    `expert eye', that are bound together in the contemporary `reading' of border scans. Thegrowing corpus of security professionals are key players in the government of mobility

    at the border and in technologies, not least where images such as those in Backscatter

    appeal to the expert eye.

    In contemporary homeland security practices, then, there is a reliance on tech-

    nologised visualisations to augment and exceed human vision and to decipher the

    indisputable `electronic footprint' that people are believed to leave behind (de Goede,

    2003). The use of Backscatter insists that the most faithful facsimile of the image of a

    person is to be found in X-rays scattered to produce a shadowy image or likeness of

    a body. This insistence finds parallels in the physiognomy of Lavater, which sought todetect ``hidden causes legible only by specialized interpreters'' through medical diag-

    nostics that scrutinized people's appearance (Stafford, 1991, page 84). Lavater's expert

    reading of his subjects' silhouettes sought to probe ``their every passion, the seat of

    its residence, the source from which it flows, its root, the fund which supplies it'';

    by ``piercing through [all] coverings into his real character'' to visualise the ``foreign

    and contingent'' aspects of a person, he sought to ``discover solid and fixed principles

    by which to settle what the Man really is'' (Lavater, 1792, cited in Stafford, 1993, page 95).

    Note also, then, the appeal to visualising true character and behaviour, made by US

    Secretary for Homeland Security Michael Chertoff, more than 200 years later:` We use this data to focus on behaviour ... . It allows us to move beyond crude

    profiling based on prejudice, and look at conduct and communication and actual

    behaviour as a way of determining who we need to take a closer look at'' (Chertoff,

    2007).

    Like the physiognomist's silhouette, the 21st-century data shadow, expertly read, is

    thought to reveal the most hidden recesses of a person. In Chertoff's speech on the use

    of airline passenger name records (PNRs), the data are offered as a means of visual-

    ising a person long before an actual physical border is reached. Forensic approaches to

    data mining in the war on terror are offered as a means of looking inside a hiddendomain, prising a person apart in order to examine component bits and bytes of data

    which feed into wider screening, profiling, or identification calibrations. The aim is to

    conjure an image that can form the focus of our `vigilant visuality' (Amoore, 2007).

    Taking people apart: digitised dissection and the body at the border 453

  • 7/28/2019 Amoore Hall 2008 Taking People Apart

    11/22

    Contemporary security projects of visualising risk and anomaly bear a striking

    similarity to previous attempts to locate deviance in bodies. Francis Galton's attempts

    in the 19th century to produce a physical `type' for identifying criminality anddegeneracy involved the overlaying of multiple exposed photographs of criminals.

    This allowed a ` composite portrait'' to emerge, one which removed all need for

    fallible human judgement by utilising mechanised abstracting procedures: ``Murderers

    or violent robbers could ... be brought into focus so that the archetypal killer could

    appear before our eyes'' (Daston and Galison, 1992, page 103). The anthropometrics

    and criminal anthropology of Galton, and others such as Cesare Lombroso, appealed

    directly to the contemporary belief that hereditary degeneracy threatened the very basis

    of social order ideas which would crystallise in the eugenics movement (Pick, 1989).

    The effort to visualise deviant tendencies from abstracted bodies and to locate identi-fiability in the body's specificity led to the fingerprint identification method (pioneered

    by Galton) and the science of biometrics. The new digital abstractions at the border

    also generate composite' projections, visualisations of risk which speak to the con-

    temporary absorption with `the war on terror', but which resonate with previous

    projects.

    As new ways of visualising and knowing bodies become possible, so the credibility

    of older visualisations is shaken and altered. The 19th-century discovery of X-rays,

    for example, did not merely advance medical technologies of seeing and diagnosing:

    X-rays also challenged the credibility of subjective senses (sight, touch, hearing) inmedical `imaginations of the interior body', shifting the gaze of the observer to one

    that externalises what is internal (van Dijck, 2005, page 5). The capacity of the medical

    practitioner's touch to take a pulse, measure a foetus, detect fever was displaced by

    a new and dominant scopic regime. Contemporary drives to eliminate tactility in the

    observation of the body have similarly abstracted the visual from its relation with

    the other senses. ` On closer inspection'', writes Mitchell, ` all the so-called visual media

    turn out to involve the other senses, especially touch and hearing'' (2005, page 257).

    Visualisations cannot avoid their entanglements with other sensory practices. And yet,

    it is also clear that through the scopic regimes of modernism ``touch has been elimi-nated'' (Stafford, 1993, page 131): ``we are prohibited from touching'' (Mitchell, 2005,

    page 260); and ``the tactility of visuality is denied'' (Elkins, 2002, page 95).

    As all sensory data are folded into the visual, and thus become subject to the

    regimes of visuality, touch itself drops out of the possibility of knowing `other' bodies.

    Indeed, the Backscatter is offered commercially as ` hands off screening'', somehow

    distinct from an ``invasive pat-down search'' (Rapiscan Systems, 2006; TSA, 2007). Like

    the X-ray before it, Backscatter brings to the fore questions about bodily boundaries,

    between what is `public' and what is `private'. Early 19th-century X-ray technologies

    were believed to be able to visualise the ``secrets of the heart'' (van Dijck, 2005, page 93)and were associated with erotic revelation, as the (male) gaze penetrated (female)

    clothing and skin (see Cartwright, 1995). Similarly, discussions of Backscatter in the

    mainstream popular press have focused on its transgressive, titillating potential: it was

    described in the Daily Mail as ``a disturbing new screening system with the amazing

    and unsettling ability to strip the human body and reveal its most intimate curves''

    (2006).

    More importantly, as the prohibition of touch further positions the visual realm as

    that of the distanciated observer the screener in the separate building; the closed-

    circuit television (CCTV) image read by algorithmic technology; the data-led decisionon the border guard's screen so also, ultimately, the observer falls away, to be

    replaced by a calculation. In his account of 19th-century physiologist Etienne-Jules

    Marey's mechanically produced images of body movements, Joel Snyder insists on a

    454 L Amoore, A Hall

  • 7/28/2019 Amoore Hall 2008 Taking People Apart

    12/22

    careful reading of what happens when human sensory observations and illustrations

    are supplanted by mechanical monitors. Discussing Marey's sphygmograph (pulse

    writer

    designed to replace the conventional means of taking a pulse by touch)

    andin a critique of other accounts of scientific images of the body (cf Daston and Galison,

    1992), Snyder does not see the sphygmograph replacing what was previously available

    only to the subjective human senses. Instead, he suggests that ` the displacements

    registered by mechanical monitors and traced by clockwork-driven inscribers fall out-

    side the scope of human sensibility.'' ``Consequently'', he argues, ``they do not permit

    even the possibility of human intervention'' (1998, page 380). If Snyder is correct, then

    the implications for our argument here are considerable. If imaging machines now

    translate ` information that is simply not of the order of the visible'' into readable

    form (Richardson and Harper, 2006, page 7), and when the face-to-face visual profil-ing of people is apparently replaced by technological monitors, is the picture that is

    produced actually outside the scope of human intervention? Could it be, as Snyder

    suggests, that the move is to ``eliminate reliance on observational schemes that were

    incapable of resolving the details of swift displacements'' (1998, page 387).

    The scientific visualisation of the body, then, does not simply perform the objectivity

    of a distanciated eye but, perhaps more significantly, makes possible new ways of

    seeing which are not otherwise available. Technical optical enhancement does not

    simply make visible that which is normally invisible, but (through graphics of data

    readings) conjures ``that which would never be available to vision'' (Richardson andHarper, 2006, page 1). In the case of border scans, it is not that the observer or

    screener is removed to a remote booth, but that his or her very decision is replaced

    with a calculation already visualised. If this is the case, then contemporary visual-

    isations of the body at the border propose a resolution that is both profoundly political

    and deeply depoliticising. They operate on and through dissected and finitely differ-

    entiated categories of people, and yet they never confront the political difficulties

    of that which cannot be seen or resolved. Instead they ``bring us into a domain we

    cannot see'' and they ``authorize us to make claims about what we see'' (Snyder, 1998,

    page 395). Just as the Backscatter deploys the residue or excess that is left over in aprocess quite literally that which is `scattered back' so visualisations of the body

    at the border, placed alongside other data traces and risk profiles, seek to capture that

    which exceeds the practice of looking itself.

    The histories of scientific illustration are replete with examples of techniques

    deployed to make visible, and to record, that which would otherwise be invisible. The

    practice of representing together multiple angles, planes, and perspectives of a single

    physical entity the `assemblage' visual method appeared to produce new knowledge

    from the component elements. The `exploded view' of an architectural plan, an assem-

    blage view of an organic structure in a botanical illustration, or engineeringdiagrams, offers ` attenuated lines'' and ` distant viewpoints'' (Elkins, 2001, page 18).

    These assemblage images of science of scattered and dissected component studies

    with careful measurements, weights, dimensions, and angles which are drawn into

    association give the appearance of a whole that can be viewed from all perspectives.

    Elkins, writing on the `geometricisation' of the scientific imaging of minerals, however,

    reminds us that these are not multiple perspectives on a single whole, but precisely

    projections of something that would not otherwise be seen. ``Projection subverts the

    viewer's capacity to understand [the] drawings as representations of three-dimensional

    objects'', writes Elkins, ``because it flattens and distorts forms without seeming to doso.'' What may seem like enhanced perspectives familiar, solid, life-like even are

    for Elkins ` unexpectedly compressed'', requiring ` mental expansion to correspond

    with our anticipations of perspectival convention'' (2001, page 21). Thus, the historical

    Taking people apart: digitised dissection and the body at the border 455

  • 7/28/2019 Amoore Hall 2008 Taking People Apart

    13/22

    problem of translating the solid spatiality of bodily flesh onto the two-dimensional

    pages of the anatomical atlas is apparently overcome in the contemporary form by

    the virtualised, screened, and projected reconstructions of bodies.The pictorial scientific assemblage, then, as in Jacques Deleuze and Fe lix Guattari's

    assemblage, `holds together' multiple heterogeneous elements as though they were

    associated (1987, page 357). In order to be seen as a whole body, the images need to

    be `projected' and expanded, losing their perspective in the process. This visualisation

    of the invisible whole took on new dimensions with early 20th-century cinematic

    screening techniques. Cinematic projection is produced from fragments of visual

    data, individually isolated elements that are selected, differentiated, and reintegrated

    into a visual whole (Kittler, 1997). As in the scientific assemblages, gaps in perspective

    exist between the isolated fragments. These gaps are filled, though, with the projectionsof the observer, giving the impression of a seamless whole. A projected body, then, is

    effectively inferred from abstracted, partitioned, and compressed components. Joseph

    Pugliese (2006) argues that the space created by the ``retina lag'', as the eye apprehends

    these compressed fragments, is intensely political, possibly subject to ` a racially

    inflected regime of visuality [which] inscribes the physiology of perception'', producing

    a ` persistence of vision'' which results in misrecognitions of many kinds migrant

    workers for `terrorists'; friends and neighbours for `known associates'; Islamic youth

    groups for `training camps'. As Donna Haraway (1991, page 190) argues, all eyes,

    including technologically enhanced devices, are ` active perceptual systems, buildingin translations and specific ways of seeing''; there are no unmediated images, only

    ``highly specific visual possibilities''.

    It is precisely the visualisation via dissection and projection, we suggest, that charac-

    terises the contemporary treatment of the body at the border. The combined scientific

    assemblage of component parts data, electronic fingerprints, iris scans, automated

    risk scores, pixilated body images and the screened projection of the resulting whole,

    appears to render the individual transparent to the external gaze. The US Air Transport

    Association's translucent `Clear Card', for example, as well as the UK's `Fast Track'

    glass screens within Heathrow's terminals, both represent the unimpeded vistas of theprescreened and transparent `trusted traveller': an apparently clear view that is afforded

    by integrated computer databases and biometric identification. ``The computer screen'',

    writes Anne Friedberg, ``is both a page and a window, at once opaque and transpar-

    ent''. The multiple layers or ` windows'' of software appear to ``transform the screen

    surface into a page with a deep virtual reach to archives and databases, indexed and

    accessible with barely the stroke of a finger'' (2006, page 19). Understood in this way,

    the digitised and dissected fragments of a person that are produced, layer upon layer,

    via the windows of data images, scanned X-rays, screened profiles of past behaviour

    and transactions, give an illusion of seeing the depths of a whole person `without racialprejudice' (Chertoff, 2007). Like 19th-century scientific assemblages, the atomised

    elements are stretched, compressed, and reduced in order to project a whole that could

    not otherwise be seen. Abstracted pieces of a person are taken apart, drawn into

    association, and displayed together on the border guard's screen; inside databases

    to be stored for forty years; within algorithmic calculations of a person's `risk score'

    as though they could only ever belong together.

    The secret and the private

    What, then, are the implications of reading the contemporary technologised visual-isations of the body at the border in light of the genealogy of corporeal dissection and

    imaging we have presented? What is at stake in framing digitised bodily disclosures

    as matters best addressed by recourse to `rights' and `privacy', as current critical

    456 L Amoore, A Hall

  • 7/28/2019 Amoore Hall 2008 Taking People Apart

    14/22

    challenges seek to do? The genealogy we have traced reveals contemporary somatic

    probing and visualisation at the border to be part of a longer history of `body knowl-

    edge'

    as a territory to be mapped, a container for unknown motives and secrets,a canvas from which character can be discerned. More specifically, the body has

    revealed itself as an entity from which order, certainty, and essence can be extracted,

    so long as the gaze is `objective', `expert', or `unimpeded'. We draw out here three key

    consequences of the arguments we have made.

    First, management of risk in the contemporary `war on terror', through excavations and

    dissections at the border, involves bodily (re)bordering processes, processes which threaten

    to slip away from contemporary political debate. We have shown that the history of

    dissecting and dividing the body is a history of boundaries, excavations, abstractions,

    and reborderings which seek to conceptualise and visualise a `whole' and so demarcatewhat is understood to belong to the self and what can be scrutinised `in public'. Thus,

    the debates about privacy and rights within screening and imaging practices reinvigo-

    rate the Western, modern view of an individual as sovereign possessor of selfhood,

    clearly embodied, and whose freedom comes from ownership of his or her person

    and capacities (Macpherson, 1962, page 3). It is from this distinctly Western and

    modern concept of personhood that terms such as `dignity', `privacy', `autonomy',

    `self-determination', and `freedom' make sense. Privacy, then, hinges on the idea that

    there is a sphere ``not of concern to others'', the invasion of which strikes at a person's

    autonomy (Lukes, 1973, pages 66, 133). The idea of `dignity' (often cited in rights-basedcritiques of scanning and screening technologies) is related to this idea of a private,

    autonomous self, but also to a more nebulous concept of human worth that exceeds

    any attempt at division or differentiation. According to Martha Nussbaum's neo-Stoic

    perspective (2001, page 359), this worth, at heart, asserts that all humans are funda-

    mentally equal by virtue of their capacity for reason and should thus be treated with

    respect an acknowledgement of that equality. The stripping, exposure, and `writing' of

    a body involves violence, as we have seen, but also a reduction of the person. Previously

    unimaginable political interventions become possible with the reduction of people

    to `bare life' (Agamben, 1995), naked in real or metaphorical terms. Thus the demandsfor ever-more-penetrating bodily disclosures at borders strike at the heart of dignity

    in a way that is hard to pin down in debates about `acceptable' intrusions of privacy,

    or the use of data.

    Border scans bring into focus the collection of data as well as its subsequent use

    and circulation. The political contestation of bodily screening and visualising draws

    on conceptualisations of the private self which trace a `self-evident' boundary around

    the body, intrusion into which threatens `integrity' (van der Ploeg, 2003). Many of the

    privacy-based challenges to body-security interventions focus on the intrusiveness of

    gathering body data, where intrusiveness is related to the piercing of bodily boundariesor exploring bodily orifices. Irma van der Ploeg (2003, page 67) argues that running

    through these debates is ``a particular ontology dichotomy'' whereby ``integrity'' applies

    to the fleshy physical entity and ``informational privacy'' is presumed to cover all digital

    representations. In an era of informatised bodies, however, the distinction between

    materiality and representation is less distinct. DNA information, for example, is not

    a representation, but a trace of `body-as-data' from which a detailed profile could be

    generated. Technology, then, alters ``the boundary, not just between what is public and

    private information but ... between what is inside and what is outside the human body''

    (van der Ploeg, 2003, pages 58, 70 ^ 71). Our delineation of the history of visualisationand dissection has revealed that the practices of corporeal dissection have intertwined

    with, and even facilitated, the emergence of the concept of the whole, distinct, and

    separate body and self to which `privacy' might relate; abstracted conceptualisations of

    Taking people apart: digitised dissection and the body at the border 457

  • 7/28/2019 Amoore Hall 2008 Taking People Apart

    15/22

    whole bodies were made possible only through their disintegration. Just as art and

    science cannot be separated in early anatomy, so the histories of the partitioned body

    and the unified body are conjoined. The `scattered', digitised images of contemporarysecuritisation practices conjure a body that is no longer bounded fully by skin, but

    which is intimately intertwined with information systems.

    Backscatter is part of the proliferating visual practices through which risk is

    `stabilised' by technological enhancement (Feldman, 2005, page 204). We have argued

    that what is at issue in the visualisation of the `risky' subject is not only the potentially

    discriminatory `sifting' of mobilities, life chances, and possibilities at the border (Dodge

    and Kitchin, 2005; Graham, 2005; Lyon, 2003). Instead, we have argued for attention to

    be paid to the violent tendencies of these technologies, which emerge from the processes

    of abstraction and disintegration, and the effacement of personhood. When everypassenger is reduced to ``a holographic composite ... of gestures, data and algorithms''

    (Feldman, 2004, page 340), it is the normalisation of demands at the border (to unveil,

    confess, flay, expose) that forms part of the violence of the border scan.

    Second, the appeal to protect the individual's rights to privacy takes the body to be a

    sovereign territory that can be secured. In this specific sense, paradoxically it mirrors the

    homeland security state's claim to the right to conceal, and to draw exceptions in order

    to secure and to protect. And so, as philosopher of law Costas Douzinas reminds us,

    there is a difficulty for ``critical academics'' in ``reconciling their occasionally scathing

    theoretical critique of rights'' with the practice of ``radical lawyers who mobilize rightsdiscourse to protect the underprivileged and oppressed'' (2002, page 380). There can be

    little doubt that some of the most significant political challenges to contemporary

    treatments of the body at borders are coming from critical lawyers, many of whom

    represent those people most subjected to racism, prejudice, and violence at the border

    (cf Hosein, 2007; Rotenberg 2003; 2007). For Douzinas, one possible critical route

    into this problem is to consider the appeal to rights of many kinds privacy, bodily

    integrity, a private family life, freedom of expression to be one specific struggle

    for recognition, a legal claim to human identity. Because the liberal rights tradition,

    though, recognizes the `Man' in human rights only by abstraction

    and often collapses`man' with `citizen' (Arendt, 1958) the legal contestations we see tend to reproduce

    precisely the reduction that we have argued exists in digitised dissections at the border.

    Put simply, the abstractions that are made in the defence of people's rights to privacy,

    just as in the digitised imaging of the body, risk recognising only a facsimile of a person.

    The reduction of a person to their rights recognises, as Douzinas puts it, only ``a non-

    substantial, a thin personality, a public image that seriously mis-matches people's

    self-image'' (2002, page 397). This leaves people, as one of us has argued elsewhere,

    contesting the identification that is made of them, both in law and in security practice

    (Amoore, 2006).The demand for recognition cannot be substantially satisfied by a mode of privacy

    which stops at the surface of the skin, seeking coverings, veilings, legal entitlements,

    and ownership of personal data. As we have argued, the territory of the body is

    differently visualised over time, never residing strictly at the surface or the skin.

    Now, we are seeing a pervasive enmeshing of the body's interior and exterior, the

    spiralling out of images of the inside, and the incorporation of digitised images,

    data-based risk profiles, and biometric markers, as though these could make visible a

    `whole body'. What does the right to privacy or bodily integrity imply in this context?

    If the contestation of new border security techniques becomes a battle over the body'sterritory, we suggest that there is profound uncertainty as to what the limits of

    that territory may be, how it is bounded and enclosed. As the boundaries of the

    body and its multiple interiors become entwined with data profile images, risk scores,

    458 L Amoore, A Hall

  • 7/28/2019 Amoore Hall 2008 Taking People Apart

    16/22

    and other visualisations, can we meaningfully delineate the literal stripping down of the

    body in Backscatter techniques from the raw dissected data images that are stored

    alongside and used to identify invisible threats? Held together in an assemblage, asthough they could only ever belong together, the pixelated fragments of the Backscatter

    image provide another layer for the ever-hungry integrated borders databases.

    Certainly the `nakedness' of the stripped-down man in the `rights of man' (Douzinas,

    2002, page 398) is not politicized by the continual redrawing of a legal boundary. It is

    this redrawing that runs through most of the current appeals to privacy: ``the infringe-

    ment on privacy must be proportionate to the security threat''; ``the collection and use

    of personal data must be transparent''; ` subjects must be informed if they are on a no-fly

    list''.(5) It is appeals of this kind that occupy what Jodi Dean has called ` counter-

    publics'' who become involved in ``an excessive sub-dividing that repeats the problemsof boundary-drawing'' (2003, page 373). In contrast to a redrawing of lines, what is

    needed is a denser and more complex sense of privacy one that is capable of living

    with the political, the very difficulty and irresolvability of the problem of recognition,

    and one that interrogates the very drawing of the line itself.

    Finally, the contemporary visualization of the body at the border is not primarily one

    of surveillance, but of projection. As we have shown, the image is one that is projected

    forward in time, seeking to capture something or someone as yet invisible and

    unknown. As we have argued, and in contrast to the idea of the subject completely

    and wholly surveilled, it is well established in the literatures on imaging in the arts andsciences that projections rely upon the gaps in an apparent whole gaps that can never

    be recovered. Put simply, it is a series of misrecognitions that make it possible to claim

    singularly to have identified a person. If this is the case, then there is a fundamental

    problem for those who would challenge by demanding access to some kind of full

    picture. The gaps which are integral to the projected visualisation of a person the

    absolutely unrecoverable gaps are everywhere sought by those who would challenge:

    `this person is misidentified as a risk'; `we have the right to access the data that is held

    on us and to seek redress where it is inaccurate'; `access to the full picture of a person

    should be restricted to named agencies'. These are impossible claims because, althoughtheir authority is founded on individual rights, the subject of the projected body is a

    facsimile, an image, a digitised doppelganger. The demand that the body give up its

    secrets, that all must be `flayed' and disclosed at the confessional border (Salter, 2007),

    can never be politically unsettled by a mirror demand that the authorities disclose what

    they have seen. In many ways, disclosure is working on both sides of the relation

    the homeland security state seeking a means to make the invisible visualisable, and

    those who deploy privacy rights demanding access to, and protection from that which

    is seen.

    If the counterappeal to disclose the making of the projected body, then, fails topoliticize the question of digitised dissections, what precisely would need to be con-

    tested? A reading of Douzinas would suggest that it is with the very misrecognitions,

    the ``projected false, inferior and defective images of self'' both within liberal legal

    traditions and, in our terms, in the identity-voracious security state that we should

    begin (2002, page 383). Inside the reductive claims to bodily integrity and personal

    privacy, Douzinas suggests that there is an occluded `real me', a complex and contra-

    dictory subject, whose actual experiences of violence and degradation are exceeded, and

    yet never fully recognised, by an abstract legal principle. The juridical claim to right

    of privacy contains a quite unique paradox. It makes a public demand for recognitionfrom others, and yet it renders these private and retreats from the difficulties and

    entanglements of politics in face of the other. A more complex and embodied sense of

    privacy, rather than incorporating difference into universal entitlement, would need to

    confront exactly the intractable difficulty of recognition of the other and by the other.Thus, for example, the question of what to do with the `noncitizen' who cannot appeal to

    the nationally framed privacy laws forever circles the juridical debate. A more nuanced

    sense of privacy would see that it is in the drawing of ever more finite and granular

    categories of bodies (and, therefore, categories of the private), that the very claim to

    citizenship is suspended.

    Conclusion: digitised dissections

    ` [Y]ou have all these complex policies and complex issues and the best way to put a

    brand on it is privacy ... . It's still very much an issue, it's still the fence being foughtover, it's still the thing being negotiated ... [Y]ou've got to admit they're getting

    very, very clever at thinking these problems through, such as the privacy friendly

    data mining ... [I]t gets harder and harder to say this is a privacy invasion, how

    do you justify that when your opponents are becoming, in their privacy awareness,

    are getting more and more clever? ... [N]o human being is involved in deciding

    who and who is not a terrorist, it's all a computer, so not invading your privacy

    until you're flagged and then a human interferes.'' (6)

    For those involved in drawing `the battle line' for contesting the expansion of digitised

    security `solutions' at the border and beyond, the manner in which technologies such asBackscatter scans (as well as iris capture, data mining, and risk profiling) problematise

    `privacy' is a matter of real urgency. If the visualisation and visibility of the body at the

    border are `a question of human dignity', how can the indignity created at the border

    remain at the centre of critical challenges? Can contestation formulated around privacy

    encircle the potentiality of border scans, screenings, and projections, the demand for

    authentication, the precise metric of the bio that is at work? Is dignity secured by

    privacy? For some working in the field, a whole focus on the biometric (as identifier)

    leads away from the key issue: ``trying to make it more about the database than about

    the biometric''(7)

    that is the retention, sharing, and use of data.Yet it is clear that processes of disclosure, visualisation, and projection of the body

    are key to contemporary securitised borders. As we have shown, the history of know-

    ing the body via taking apart has always been a history of security or, more exactly, of

    securability. Within the public rituals of dissection from Renaissance anatomy theatres

    to contemporary digitised extractions lies the seductive idea of securing identity. If the

    visceral and bloody depths of the body could only be excavated to reveal true disposi-

    tion and credibility, and if they could be expertly recorded and visualised, then identity

    itself could be rendered securable. Dissection practices, then, hold a potency derived

    from the promise of securability in an uncertain and capricious world. It scarcelymatters whether the specific knowing of the body (and its `risks') by visualising its

    depths and recording its traces meaningfully `resolves' the problem of security. As in the

    genealogies of body knowledge we have discussed, it is the process of mapping of

    the territory of the body itself the classification of bodies or silhouettes into degrees

    of risk, normality, and deviance, the identification of a threatening presence at the

    border from abstracted aspects, the capacity to project a facsimile of a body forward

    in time which characterises contemporary digitised dissections and which drives their

    prominence in the public rituals of security. The `identity regime' that is emerging is

    of particular concern to those who have a local level concern with raising awareness

    about the burgeoning use of biometric technologies. As one activist at the No Borders

    Camp 2007 (8) remarked, a critical preemptive language must be built around refus-

    ing identity and authentication regimes of all kinds: rather than simply resistingbiometrics, there must be contestation built around a recognition of the ways in

    which people move and shift between the spaces spaces increasingly marked out by

    digitised identity authentication, data profiles, risk scores, and legalistic interventions

    around rights.

    The contemporary technologies that bring the body, its traces, and parts, into

    focus and the entanglement of these technologies with the politics of migration and

    security signal a decisive and novel direction and challenge. The contemporary visu-

    alizations of the body at the border operate on and through partitioned and finitely

    differentiated categories of people, and yet they are quite literally and physicallyremoved from the political difficulties of decision. Where border agents view their

    screens from a distance, seeing not `real' people but data-based risk scores, chalk-line

    scans, algorithmic models, then where is a judgment actually made? What are the

    ethics of a decision taken on the basis of prescreened and visualised elements of data

    on a person? Certainly, as we have argued, and as the evidence from advocates and

    activists suggest, such questions pose new problems for the recourse to rights of

    privacy or human dignity. There are, of course, very real benefits to be gained through

    legal challenge, particularly for those most targeted or marginalised, but there is also

    something more at stake, a question of the way life itself is governed that is now indanger of slipping out of the debate.

    In this paper we have pointed to some of the difficulties that critical responses to

    technologies such as Backscatter must confront. Their logics can never be disrupted

    wholly by an appeal to surveillance or the shielding of the body from the surveillant

    gaze. As Michel Foucault declared in his late lectures at the Colle ge de France, ``the

    panopticon is completely archaic, the oldest dream of the oldest sovereign'' (2007,

    page 66). The newest dream of the youngest sovereign, then, is not one of disciplinary

    surveillance that ``concentrates and encloses'', but one of an apparatus of security that

    sees differential risks and normalities, ` opens up to let things happen'' (pages 44 ^ 45).While challenges to biometric borders and invasive imaging call up the sovereign

    territory of the body, border disclosures that take the body apart function as just

    such a security apparatus that transcends and transgresses corporeal territory. Digitised

    dissections, understood as visualisations that project fragmented and reduced elements

    of a person, are posing profound new questions of the political geographies of bodily

    boundaries and shifting the terrain for those seeking to challenge their governmental

    implications.
