Me, I wouldn't mind life without parole for trash like this, but only if:
(1) They're thrown into an Alcatraz-like hole with only other lifers there. We could reopen Alcatraz and build others in similarly impossible-to-escape-from places (I'm thinking Aleutian islands, or perhaps Kahoolawe in Hawaii).
(2) NO contact with the outside world (you go there, you don't come out except in a pine box and you'll be utterly forgotten when you do).
Actually, I like that idea. And - no cells either. Just a big wall around it, and it's all general pop. You can be the king, or the b***h for the stay, it's up to you. But hell never the less.
Let them finish the bomb disposal then send them to the farthest islet in the Aleutians.
