I really don't know a good solution to the schools.
I mean if we let the teachers have guns…one kills a black student because he/she got attacked by them?
Here comes black lives matter, protesting, trying to harm the teachers and/or burn down schools.
Put a bunch of guards around them and it starts looking like a prison and becoming a police state like martial law. Mainly because it won't stop there. We will have guards everywhere.
Damned if you do, damned if you don't.
