Well of course they do, that's because they can't kill them. What a maroon.
I have always loved it when the anti-death penalty people talk about how it is not working as a deterrent therefore it should not be used. I then point out that the death penalty is not a deterrent, it is a punishment. Prison is also a punishment even though some try to say it is a deterrent. The concept of the prison was created thousands of years ago and yet we still have crime. Anything the justice system does to a convicted criminal is a punishment not a deterrent. Deterrents to crime come from society before criminals committ crimes. After that society punishes the criminal act. I don't understand why that's such a hard concept for so many on the left.
