Agreed. It's the same as when they were confiscating nail clippers at airports. Too many things can be made into a weapon that you just can't stop (a sharpened belt buckle point, or the whole belt, a tightly rolled magazine, a edge-sharpened credit card, etc., etc. etc,—too many thing to check for). Why not weed out the violent kids (oh, maybe because that takes diligence and effort?).<br><br>
