Okay, I misread.
I for one am for the death penalty, but even one innocent killed in the course of justice makes a mockery of the whole system. ALso the death penalty is expensive after you include all the costs of lawyers, judges, and the like, both in time and money. I like GUard Dog's sentiment. Those who have life imprisonment without possibility of parole get sent to a super max prison and kept in a 7.5 by 7.5 foot stone cell where they never see the light of day again.
