justice is less than perfect. I have never said, nor even implied that it was OK to send an innocent person to prison for life with no parole. I think that is absolutely heinous. The significant difference, of course, is that is NOT irreversible. If you execute someone today and then find out tomorrow that you screwed up - if an eye witness recants, or a new piece of exculpatory evidence is found after being misplaced in the evidence locker, or if someone is caught in the act of committing a similar crime and has, in their possession the murder weapon from the former case that had never been found, or any other of a host of events that might happen to cast doubt on the guilt of a defendant, "ooops" probably will not fly as an acceptable excuse for their family. If, on the other hand, any of those things happen and the formerly convicted person is serving life instead of becoming worm food, the state car reverse its error. Is that really so hard to understand?
