You suspect my solution to angry people is to ban weapons?
Not sure how much more I can clarify. I am sure a large part is
it's come to a CYA situation for these schools. I don't think people assume that angry people are all mass shooters, but their protocol is to treat them like they are I guess. I just thought the level of shutdown was a bit much, and like I said - along with the active shooter drills they have to do now (of course their's was today), I am not sure what this is doing to the mental health of the kids in the school, but I would hazard a guess
it's not a net positive.
I would also hazard a guess that the school isn't nervous that the kid who left was going to get a baseball bat, poison, or his car.
