Well, my question was answered. When viewed as a positive means of identification, DNA testing makes sense. I guess my problem with it is the extent DNA can be used to screw up a person's life beyond simply identifying him. What restraints are in place to see to it that the DNA samples are not used for research purposes? Or to determine genetically transferred diseases? I personally know people who refuse to be tested for diseases such as Crohn's for fear that a positive test result will cost them or their children a lifetime of health coverage.

What limits are there to prevent government funded use of "felony related" DNA to "prove" the existence of a "Bad Seed" gene or whatever? Paranoia? Seems to me I remember government funding of studies on black prisoners deliberately (and without permission or patient knowledge) infected with syphilis.

Maybe I am just not getting enough sleep.
