That's not necessarily an argument for the death penalty. It's just an argument for making sure that a life sentence really is a life sentenceBe sure? If they are alive, you can't ever be sure and you know it. Just imagine how the parents of that 16 year old must have felt when the dirtbag got out.
How can you ever be sure of anything when it comes to governments and laws? They always change. But dead is dead and revenge is a good thing.
