• Serial murderer: 5 murders in 18 months
Use of DNA in case…
• DNA dragnets:– “voluntary” samples– Disposition issue
• Development of racial profile from DNA– DNAprint genomics
• Suspect caught because his DNA was collected because he was suspect in another case and his DNA was matched to DNA from crime scene.
• Extensive criminal history
Issues
• State/society versus individual
• How to organize the state
• Equity
Individual vs State
• Surveillance: location and genetic• Who should be subject to this surveillance?
– Violent felons?– All felons?– Arrestees– Suspects?– Easily available… dragnets, databanks, etc– Everyone?
Equity: Who should be subject to this surveillance and why?
• Who should be subject to this surveillance?– Violent felons? All felons? Arrestees? Suspects?
– Easily available samples?
– Everyone?
– Currently: in UK approx 1 in 10 men in database, and in US 1 in 50 men.
• Why?– Deprivation of rights vs probabilitistic logic
(Kaye/Smith)
Genealogy as Investigative Tool: The case of Lynette White
• Stabbed 50 times on Valentine’s day, 1988
The case of Lynette White
• The Cardiff three
• But convictions were thrown out…
The case of Lynette White
• Case re-opened in 2000
• …and spots of blood were found on skirting board.
The case of Lynette White
• DNA searched against the database.
• No matches.
• Examined “near-misses”: 600 people 70 a 14 year old born after murder
• DNA matched uncle of 14 year old, Jeffrey Gafoor
Genealogy as investigative tool
• One allele match per locus, Y chromosome, mtDNA matches
• Increased precision with increased number of loci
• FSS sells “familial searches” for 5000 pounds.
Genealogy as investigative tool
• How many people would under de facto surveillance?
• Legal issues under deprivation theory
• Upsets political balance
State/society vs individual
• Empowering the state to protect individuals
• Limiting the state’s ability to abuse individuals
• What is the architecture of trust?– Can’t depend on wrong doers to take pictures
and videos of their acts
Constraining the State
• Disempower the state– Minimize/eliminate databanks/databases
• Regulating the state– Selectively disempower (e.g., sample retention)– Rules– for both people and technologies– Transparency
• Restructuring the state– Buffering forensic scientists– Institutionalizing “guardians of privacy”
Other big issues…
• Finality– Post-conviction: 143 exonerations– Statutes of limitations, “John Doe” warrants
• Reflection– Exonerations– People that should have been caught
• Behavior, genetics, and criminal justice
Pushing the conversation forward
• Picking up the baton from the National Commission on the Future of DNA Evidence
• What do we know? What do we need to know? What are the trade offs?
