I have none. If a murderer, or say a child rapist is put to death there is a 0% statistical chance of recidivism
Not only do “dead people tell no tales”, they don’t commit crimes either.
For those that are opposed to the death penalty, perhaps you should work to change the parole laws so that “life in prison” means “life in prison” -
otherwise, you’re simply sentencing these criminals’ future victims to death instead of the criminal himself.
