The use of DNA evidence in the courtroom had its big coming out party back in 1994, with the infamous bloody glove in the O.J. Simpson trial. Today it’s commonplace; just last week we learned that children seized from a Texas ranch run by a polygamous sect will get DNA paternity tests to see if sexual abuse went on there. It’s a reality of today’s courts: Genes themselves are regularly called upon to “testify.” And there’s more to come – some claim that new DNA tests can even predict the chances that a convict, if released, will do wrong again. Washington Post reporter Rick Weiss has been writing about genes in the courts, and he speaks with Faith Salie on Fair Game.
