Just curious, and maybe I don't understand . . . but if the teacher met all the qualifications for the individual state concealed carry permit then why would that not be good enough? Afterall, it is a state's rights issue, not a federal issue, so the individual state laws would apply. Are you suggesting the teachers need law enforcement training or gun training; the two are very different. Like I said, maybe I don't understand what you are saying and I do not want to read too much into it.
I'm not sure I'd want EVERY teacher to have a sidearm, but I'd certainly support those who WANT to carry a gun, and who qualify to have a CCW permit, to have the ability to have the gun.
