I think they should carry and I've never charged a school teacher for a CFP class. The safety of our children is that important to me, and armed school teachers and employees are the perfect start to the hardening of the school target. I don't think they should advertise their armed status to students or anybody else, that's a big loss of tactical advantage should the need to use the tool ever arise. For elementary schools I've always highly encouraged teachers to take advantage of the Eddie Eagle program, whether or not they decide to carry in class, it's just a good common sense program for kids.
