Terrible idea.

It's totally off the beam of intelligence! Can you imagine a single teacher, adrenaline pumping, unlocking the gun cabinet and preparing to shoot someone who is obviously well-versed with automatic weapons? What do you think the police would assume....coming into a classroom and seeing a teacher (let ALONE a black teacher) holding a gun while children cower under their desks? This is a ridiculous attempt by trumplegroper to pass off the blame for NRA's purchase of Congress members!

But what kind of gun?

I think that when you're in the shitter and guns start going off, you're in deep do do.

A teacher with a handgun would be out gunned by a shooter with an AR15. The effective range of a handgun is probably 30 feet. But the effective range of an AR15 is probably 300 yards. A shooter with an AR15 facing a shooter with a handgun down a long school corridor would not be a fair fight. The handgun would probably miss the target, may hit an innocent bystander, and would soon run out of bullets and need to reload. The AR15 would have the accuracy at long range, have more shots, the ability to reload more quickly, and a much higher rate of fire.

only an american could have come up with that one

Fortunately, I am retired from teaching. As I said before, the idea of arming teachers popped up right after Columbine. I don't know a NYC teacher that agreed then with this suggestion. I am sure no one would agree now. Is dangerous. Very dangerous.

Just imagine what’s going to happen to that poor black teacher should the cops be called for any reason.

We use guns to protect us from bad guys. Used properly guns are great. Some are so simple minded - "guns bad" I suppose fire is bad too if its misused, maybe we should get rid of gasoline - it might explode and burn or kill you.

Its the use or misuse that makes something good or bad - teachers and admins are generally very responsible - I would trust them to not misuse their weapons.
