yep.
Nothing like getting a Dixon HB #2 shoved up to the lovely embossed lettering and snapped off in a guys eye socket to ruin a day. there are folks out there who are just plain dangerous to mess with.
I know but the problem is generally though those people aren't teaching school.
Remember the teachers/school administrators are the crowd that wrings their hands and goes "violence isn't the answer" even as they are getting slaughtered by an active shooter.
Several times in class discussions about what to do about a school shooting I raised the point of "Fight back like a wolverine on crack and you have a much better chance of coming out alive" and everybody else, every. single. time. looked at me like I had three heads. Several times similar "drills" to this have happened over the past several years and not once has anybody reacted with force.
The drive to survive just isn't there for most people...
