Well, what can they do? They'd be expelled if they pointed their fingers, or a piece of food chewed into the shape of a gun, at the criminal and went 'bang bang you're dead', They are being told only evil people want to legally own and carry guns, no mention of criminals that do that, and being told and taught that the police are to be hated and avoided, or feared and killed, so the poor kids are running out of options. How long before the lawsuit about one kid 'threatening' another kid with a can of peas crops up?
