IMO cost shouldn't even be a factor. We're talking about potentially ending the life of a person. The only factor should be justice. Guilty or not guilty? To me, it's morally reprehensible to deny a man the ability to prove his innocence and thereby save his own life because we feel him doing so may cost too much.

I agree, cost shouldn’t be a factor. But I bring it up only to show that for those for whom cost IS a factor, DNA is very cost-effective. Better to know early whether you’ve really got the right person or not than to defend your “hunch” with millions of dollars over years and decades.
