I would prefer we invest money in making the school safe by other means than counting on armed teachers.
that said, I'm surprised there are so many strong 2A people saying a teacher shouldn't carry a weapon.
I'd rather hear about a teacher shooting it out with an armed intruder than one getting shot hiding in a closet.
I'm surprised too. An armed teacher may not be able to stop an armed intruder but it sure does increase the odds that she will be able to if she's armed.
