Penalty Death
I think states should have the penalty death because it teaches others not to do wrong. If people don't want the penalty death they should not violate the laws and rules. Prosecution is a way to get rid of people who have killed and/or have done even worse things to people. Investigations are happening all over the world every minute because of people who break the law! If we just let them be in jail they have a chance to escape and go harm others again. Not all people who have killed others need to be given the death penalty, you have to evaluate the whole situation before acting out your operation. Of course this is my opinion, and I don't think that getting rid of the death penalty is very smart.
