If we really want safe schools, we should turn to guard dogs. Guns and officers may stop the carnage quickly, but guard dogs may stop things from happening in the first place.
They can be equipped with active transmitters connected to the school speaker system and trained to produce different sounds from low growl to loud bark depending on the situation and to attack when necessary.
The dogs could live at the school. With a few doggie doors and a few dog-loving staffers who wouldn’t mind a little extra pay for care and feeding, the dogs will have a home, which would make them even more protective.
