Let me clarify. I did not say that deterrence is utterly without use. When I said that there is a problem with deterrence, I meant that the current state of deterrence in our justice system is broken. There is a mistaken belief that more punishment necessarily entails greater deterrence, which is many times not the case. There is really a threshold when it comes to deterrence. There is very little to no deterrent effect of the death penalty vs. life without parole, as others have posted here. In fact, I personally find it hard to believe that a life sentence versus, say, 50 years in prison, has any additional deterrent effect for something like murder. The rational 90% would still be adequately deterred.
