I find the death penalty morally troubling as well, although I am not against it in principle. I think it should reserved for those criminals who are so psychopathic, so morally irredeemable, and so dangerous that it simply is not worth the risk to society (specifically, the prison guards who must deal with him) to keep him alive. The problem with life in prison without parole being the maximum punishment is that there is simply no deterrent for a prisoner who already has received that sentence. I suppose one could offer rewards for good behavior, but the act of withholding rewards hardly seems like a worthwhile punishment for, in the extreme example, murdering a guard or another prisoner.
That's why, though many here seem to consider me sadistic, I want punishments that get the bad person's attention and concentrate it completely,
on the vile act(s) they performed.
AND I want any police or DAs/prosecutors shown to have hidden exculpatory evidence OR faked/made up/suborned evidence/testimony implying guilt removed the same way.
For the unsure: I want the justice system to actually be a justice system.
