The Digital Witness

Duncan W. Glaholt

Question #1 : Can a Computer be a Witness?

• A: Yes!

• 1. Automatic Data Collection

• 2. Computer Animation

• 3. Computer Recreations

• Automatic Data Collection

– security pass card and log;

– cellular usage log

– any computer-based record keeping system

• Computer Animation– Computer-created representations to depict

the testimony of a witness– The classic “cut-away view”– E.g. heart valve, operating engine, piping

failure– No estimates, no suppositions, no

extrapolation– Renders evidence into animation

• Computer re-creation

– Computer-created, accurate, mathematically consistent, visual representation of what a reconstruction expert believes happened in a situation;

– e.g. modeling program, fatigue analysis, finite element analysis

Example – Flume Ride

Side Impact Demonstration

Side wall cracking

Maximum Stress Of 60 MPa

Question # 2: Are there limits?

• In the U.S.: Daubert v. Merrell Dow Pharmaceuticals, Inc., 509 U.S. 579 (1993)

• Instead of "general acceptance" in the scientific community, the new test requires an independent judicial assessment of reliability.

• In Canada: R. v. J. (J-L.) (2000), 148 C.C.C. (3d) 487 (S.C.C.):

Daubert must be read in light of the specific text of the Federal Rules of Evidence, which differ from our own;

There are a number of factors that could be helpful in evaluating novel science

“(1) whether the theory or technique can be and has been tested.

“(2) whether the theory or technique has been subjected to peer review and publication.

• (3) the known or potential rate of error or the existence of standards; and,

“(4) whether the theory or technique used has been generally accepted.

ReliabilityR. v. Chow (1991), 68 C.C.C. (3d) 190 (Alta. C.A.)

Machine collects data without human Interventione.g. recipient, length of cell phone callsProblem: No human witness available to “prove” business record under oath

Meant to be exact graphical representation of complex concept;Not based on estimates, suppositions or extrapolations;No analysis or theory added;e.g. interior of beating heart; splicing, unsplicing of DNA; inside of working engine;Problem: Shows us things no human witness could ever see

Tip # 1

Think live theatre:

A few special effects go a long way

Tip # 2

Know your audience:

Research your court and opposing counsel; anticipate and be ready for objections

Tip # 3

Strive for smoothness, rhythm and flow

Tip # 4

Remember: You are spending your client’s money, and your credibility
