How do you propose to sort out the two classes that you have indicated exist? The inability to do so perfectly is largely behind my opposition to the death penalty in general. You can't be meaningfully exonerated if you are not alive. If punishment is what people desire, the American prison system is perfectly capable of satiation. A life in an American prison is significantly worse, in my opinion, than being dead as being dead ends it immediately and life in prison forces a person to deal with the consequences of their actions for a life-time.
