I was going to walk past this but I can’t. The last thing you want in a live shooter situation is a teacher with a gun. There’s so many reasons but here’s the two big ones for me:

1. It’s really hard to shoot accurately with a short barrelled weapon. Unless you know what you’re doing, at any range beyond about 20 feet most people can’t hit the side of a bus with a pistol let alone a shooter armed with an AR 15. Soldiers and police train constantly to develop and maintain these skills. Unless the teacher is a gun enthusiast themselves, then they have no chance of mastering this. It’s made worse by the fact that the type of weapon needed in that situation would have to be large caliber. You need to drop the shooter with one shot. Anything below 9mm is pointless. If you hit the shooter with a 22 (or pepper spray or a taser) and your just gunna piss him off you’re not going to stop him. You might slow him down but it’s 5-10 minutes before a small caliber round will bring the guy down. So best case the teacher hits him, draws attention to himself and his students who now become the shooters primary target. So you give em a bigger caliber weapon that’s even harder to control and they are less likely to actually hit the guy anyway. It’s pointless.

2. Even teachers who can shoot straight aren’t trained to react in a live shooter situation. They’re teachers, not warriors. They’ll be scared shitless and are more likely to shoot themselve or their students than they are the other guy with the gun. They’d be a liability not an asset in that situation.

My daughters teacher is miss Wallace. She’s a lovely, middle aged woman and a fantastic teacher. Even still the last thing I want in a school shooting situation is Miss Wallace drawing a 9mm. I’d rather she just hid in a cupboard. It’s safer for her and my daughter.
