Yeeeah, good point. I don't even know how we'd determine that. I guess we could stick video cameras in every classroom. Since they'd be prisons already and all.

Even so, there'd be a lot of tough calls, and one thing evidence seems to suggest (but not prove, because there is so little research on this) is that people who are armed tend to make worse decisions.

Thankfully I never had to make the call, and only once in the two years I was there did anyone get stabbed.

...Only once in two years? That's - still a lot of stabbing. WOW.
