Lock them up in a real bad place for life, one that makes them wish for a death penalty. Problem solved.
I agree with the death penalty but it should have a proper study before it should be implemented because death penalty can be used in a bad manner or in a wrong way. If there's a convict we should see to it that he/she is the right suspect.
Indeed. It boils down to making sure that the person to be executed is really guilty or not. It would basically be plain murder if death penalty is implemented and innocents are being put to death instead of the guilty ones
