Big Bank Hank (look him up), no one including the "Demotard" (did you really write that?) believes that it's going to stop it all. Whitman was a trained marine (at least according to Full Metal Jacket) and those fellas are hard to stop. Nothing will stop it all. There's a death penalty for aggravated murder in several states and Old Sparky and lethal injections still happen all the time. Behavior is hard to legislate but it might help, it might save a school or two and it is hard to see how it would hurt.
