Anon I had the same questions when I heard this certain district was going that way. There are already teachers on that campus armed with concealed. How could they safely have that kind of weapon in a classroom and have time to get to it? Seems reckless to me. All of that and their playground is not fenced and wide open. I'm tellin ya, a lot of TX educators are just downright dumb.
Seems like there could be some kind of lock system in every room that any teacher could employ that would lock down every classroom door in one fell swoop.
