I've always been very much for the death penalty, but in the last few years, I've softened up on the issue. The thing that gets me is that there have been too many exonerations of death row convicts, and it usually happens after they've already been executed.
Referencing Blackstone's Ration, "It is better that 10 guilty persons escape, than that 1 innocent suffer."
Now obviously he we referring to the conviction of the innocent which in my proposed scenario would have already happened to the innocent. But I would rather keep the death row inmates alive unless there is a high level of physical evidence to prove guilt to save the wrongly convicted.
