How about just turning the convicted murder over to the family and friends of the victim. Armed, of course, with nothing other than three-tine forks (no length restriction)?
Then the family lowers themselves to the level of the killer.
Most of the time I'm against the death penalty, but in certain cases like the Green River Killer I feel it is appropriate and frankly I could care less about their rights or how they feel. If it were up to me I would make them suffer for as long as possible. They have done terrible, terrible things to women and they deserve every painful misery that can be bestowed upon them.
Barbaric? Yes, certainly. Some "people" deserve no better.
