Well when Joseph Duncan was picked up some of us had some ideas....
Nail his "you know what" to a dock and leave him there during a hurricane.
Nail his "you know what" to the top of a 110 ft telephone pole and leave him there.
Nail his "you know what" to the top of a tall cactus and attach electrodes to him.
The libs will say "listen to those right wingers they can think of some really hateful things".
