Here's a crazy idea.
Heavy on the crazy, I admit.
We put bunches of those giant magnets, the kind they use to pick up cars at the scrapyard, in the ceilings of our schools. if a gun is brought in, it trips a sensor, activating the magnets and yanking the gun out of the hand of the attacker.
And the people with belts? Or steel pins in their legs? Wouldn't work out well.
