I taught for decades in an urban school district. And I’ll estimate that maybe 10% of the attacks on teachers made it to the evening news. Our administrators weren’t very good at providing a safe learning environment. But they sure were good at covering things up.
Oh, and it was a firing offense to call the city police. You were supposed to call the school police instead. Why? The school board could bury school police reports. They couldn’t bury city police reports.
I was recently commenting in another thread that school police forces are a bad idea, as it makes it too easy for school systems to sweep incidents under the rug. Having police / sheriff’s deputies on site who are not beholden to the school system is A Good Thing.
Here in GA, we have school police forces. I was talking with a Florida FReeper, and apparently they do not. It doesn’t mean things can’t get all screwed up by the sheriff’s dept. (see Parkland), but you at least have a better chance of things coming to light.
