"The only thing that stops a bad guy with a gun," we are told, "is a good guy with a gun."
Okay. I've watched all the cowboy movies, so I know the story line, but I'm unsure. Does a "good guy" with a Glock necessarily stop a "bad guy" with a Bushmaster? Does a bored-out-of-his-mind, fifty pounds overweight retired cop stop a twenty-something psycho who knows the old fat man is kind of snoozing around the main entrance to the school building? Give me a break!
It sure as hell won't work in any secondary school, where the numerous "safety" doors are popped open by the resident youth for the sake of a smoke or a toke, and then propped open to accommodate the next "bell." Granted, the doors won't all be open at the elementary school, but, on a warm day, most of the windows will. Air conditioning is too goddamned expensive for your ordinary school budget.
Give the principal her own semi-automatic, to stop the carnage "earlier?" All the principals I ever worked for would have been pretty useless. Mine all were kind of "manly" men (and one manly woman), but they still would have shit their pants before getting into a fucking firefight. Okay, one or two would have tried the firefight even with the shit in their pants, but they still would have been useless.
I don't pretend to know the answer to gun violence in the USofA. There are a shitload of guns out there already, and I suppose the Connecticut slaughter is inspiring more sales of AR15s, just in case President Blackie Socialist tries to take away our Constitutional Right to buy them.
The only thing that stops a bad guy with a gun is a fucking lunatic with an explosive vest. Try to ignore the collateral damage.
If American gun manufacturers also produced cordite, you could be pretty sure the NRA would lobby for the Constitutional right to wear a suicide vest to your local mall, church, or youth group meeting. I mean, that's the meaning of the Second Amendment. Isn't it?
