The biggest problem with arming teachers

[unblock]

5. that may be true, but you're kinda making the o.p.'s point.

as a parent, i don't want mini-unblock being anywhere near an armed teacher who would think of him as a "pos" if he misbehaved.

i don't agree with the o.p.'s broad brush any more than you do, but arming teachers is a horrible idea for many reasons, and if you arm huge numbers of any population (e.g., 20% of all teachers in america), you're going to be handing at least some of those guns to people who don't have the right temperament for it. that number is likely vastly lower than the o.p. implies, but bad outcomes are almost guaranteed.
