I'm not sure they have them now, but suspect they might, but when I taught in Dodge City, they had a regular police officer assigned to the school. He or she didn't guard the door ad ddnt have a regular station as I understand. He was friendly and jovial to all . In no sense did one get the impression of being in an armed camp. Something the anti gun nuts are afraid of. But anyone coming in to do mischief would have him with which to deal.

Security personnel would not be dressed in tac gear . Just being their would be quite a deterrence. After all, one of the main reasons they pick schools to shoot up is that they are pretty well sure their guns will be the only ones there.

If we don't count our blessings
We are just wasting our time
