It's magic. Maybe even Voodoo. If we pass enough laws we might pass the "right" law that makes all the criminals and crazies obey the law.
That and the world is saddled with the wrong kind of folks. You know, the ones who are gumming up the progressive Nirvana because of "rights" and stuff.
It would be nice if I could end this with "[/sarcasm]" but sadly it's not possible.
