Yeah, that way they don't have to wait for the gunfire to alert them to the fact that someone has a weapon. Metal detectors without trained and armed security are useless.
Not what I'm saying at all. But you don't want intelligent conversation, do you? Metal detectors are worthless if they have no one there to stop them is my point. Do you think metal detectors automatically disarm the attacker? Get off your mommy's computer and go back to your Tide Pods.
