Matt Smith and John Gilmore recommend investigating convicted felon John Poindexter as a demonstration of his "Total Information Awareness" program:

The SF Weekly's column by Matt Smith in the Dec 3 issue points out that there may be some information that John M. and Linda Poindexter of 10 Barrington Fare, Rockville, MD, 20850, may be missing in their pursuit of total information awareness. He suggests that people with information to offer should phone +1 301 424 6613 to speak with that corrupt official and his wife. Neighbors Thomas E. Maxwell, 67, at 8 Barringon Fare (+1 301 251 1326), James F. Galvin, 56, at 12 (+1 301 424 0089), and Sherrill V. Stant (nee Knight) at 6, may also lack some information that would be valuable to them in making decisions -- decisions that could affect the basic civil rights of every American. [...]

It would be good to have an early public demonstration of just how bad life could become for such targeted citizens. Public records can be manually searched and then posted to the net by people who happen to be looking there for something else. Photographs and videos of the target, their house, car, family, and associates, can be made and circulated to demonstrate facial recognition techniques.

Employees could demonstrate denial of service to such targeted people. "You've been 'randomly' selected as a security risk, I'll have to insist that [some degrading thing happen to you]". Or merely, "I can't seem to get this credit card to work, sir, and those twenties certainly look counterfeit to me."

People who associated closely with such a targeted individual, such as their families, relatives, friends, neighbors, protective secret service agents, and business associates, might find themselves swept up in the information dragnet. Such a demonstration would graphically reveal the societal dangers of deploying such systems on a wide scale against a large number of citizens -- preferably early enough that such a deployment could be prevented, rather than reversed after major harm was caused.
