I don't see how they are protecting their citizens any more then if he had life in prison. There is no more protection, and it's still a murder, as I said above, whether a group does it, or 1 person does it. If it is not wrong for gpv. to kill a murderer than I ask you this.

Lets say someone you are really close to, lets say your son or daughter, was brutally beaten, raped, tortured and murdered. You, seeking vengence kill this person. This is no different than what the government would've done except you will now be punished. People will say that what you did was against the law and the bible. Why should the gov. be allowed to punish you for doing something that they would do if you had not.
