I think that in cases of horrific crimes, the death penalty is acceptable, or even required by retributive justice. However, I think this only applies to cases where there is absolutely no room for doubt. I also think that there really are such cases where there is 100% certainty e.g. the perpetrator was seen by many witnesses and confesses, plus as much additional evidence as you need. Unfortunately, if we only make convictions where we have the luxury of this certainty, we set the bar too high, and many guilty people escape conviction. Inevitably, under any reasonable judicial system there will be people charged for crimes they didn’t commit. But when you are charged with a crime, you are thereby unequivocally guilty, and there’s no way of charging someone with being guilty with the qualification, “he might not have done it” and another “he’s guilty of the crime and there’s no doubt”. In the eyes of the law, a guilty verdict is definitive; you did it, end of story.
Is there a problem with this either...
