Looking back on the teachers me and my kids had, I shudder when I think about teachers having guns in the classroom. One principal had mental issues stemming from a war injury in Korea and he was on the edge of nuts all the time. Several were clearly depressed, and several had serious anger issues they took out on the kids, for instance one teacher who dumped a kid out of his desk, threw things at us, and finally decked a kid he didn't like. Who will screen armed teachers for mental health issues? Can't do that without the ACLU screaming about their rights. Time to buy a ranch in Montana and home school your kids.
