Does anybody have any idea what percent of inmates could be found innocent using DNA? I'm guessing it's well below 50%. It's not like the cops needed DNA to put a coke mule away. I say test all of 'em that can be (and want to be tested) and release all that are innocent. Then check their DNA against any applicable unsolved cases where DNA would be useful.
I guess I should have been clearer. DNA testing should only be done in cases where DNA evidence would actually prove something. So maybe it should be looked at from a case to case basis and if DNA evidence could possibly overturn the verdict, it should be done free of cost to the prisoner.
I think few would disagree that I think you have come up with the "right" answer here sbane. Well done!
