Lets buy Greenland from the Eskimos. If 50,000 Greenlanders can survive there then others can too. Try 'em. Convict 'em. Give 'em a sleeping bag, a ten, a knife and a parachute ... in that order.

Why should we let them back into our society if they have proven (three strikes and you're out) that they can't control themselves?
