@blatham,
On "solving" school massacres by arming teachers, just came across this oldie on FB:
Video: Jim Jefferies, the Aussie stand-up comedian, on gun control
I'd already seen it, years ago -- it's no earnest treatise, obviously, it's all a bit tongue in cheek, but it made me laugh. And, well, the bit about giving guns to teachers, and having armed guards at schools (from 05:14 on) sure seems timely again now.
Oh, trigger warning for those of you who mind bad words, I guess -- lotta foul language in there. Good reminder that a word like, say, "c*nts" isn't equally taboo in all strands of the English language.
