Of course people have always killed each other. Cain and Abel. But if there wasn’t more of a threat of violence among teens these days, we probably wouldn’t need cops at schools.

We do not have cops at schools because there is more violence among teenagers per se.

We have cops at schools because problem students are no longer expelled and truant officers will even round up the miscreants and haul them back.
