That leaves one really effective solution: Eliminating victim disarmament zones. Nothing takes the cachet off your trenchcoat massacre more than being shot in the ear by the pink Kel-Tec .380 of Mrs. Perkins, your remedial grammar/comp teacher.
And that’s the thing! There’s no need to force teachers to play hunter/killer SWAT commando. The training requirements outlined in Florida’s hasty-ass legislation are ridiculous, and I say this as someone with a reasonably extensive firearms training resume.
The shooting problem here is the easiest possible one there is. There’s no need to go in search of anybody; just get all the kids out of sight of the locked classroom door, post yourself up in the blind spot against the wall between the doorway and your young charges, and wait. If the disturbed youth somehow manages to force the door, you send him to the respawn point like a proper camperfag.
This is the kind of snark I despair at creating, and why I read Tam religiously, on Facebook if not on her blog directly.
But besides that, it’s the only real solution to the problem of school shootings. Or shootings anywhere, for that matter.
