You gonna tell me not one teacher at one school in America is one of Ex-cop or Ex-military? It's not about "arming" teachers, it's about the idiocy of making it illegal for them to be armed.Here is the thing....you anti gun people assume that the teachers are going to run around the school doing combat rolls looking to engage the killers in a shoot out.....and you are wrong....
If there is a killer in the school, all the teacher has to do is stand in the door way of their class room and monitor their hallway.....they don't have to draw the weapon until they see an attacker enter their area.....they can then yell....."Stop, I am armed and will shoot".....from a covered position of their classroom door....the guy will run, shoot, or try to advance....if he leaves the area, the teacher stays in place...if he shoots, the teacher can draw their weapon and return fire...and if he tries to advance down the hall the teacher can draw and shoot....
All these armed teachers need to do is secure areas......they just have to wait for the police to arrive....but by being armed, they deny access to the killer/killers and slow them down....
Please, a little more thought into reality, rather than what you see in the movies.....
LOL by and large teachers aren't even doing the job they have now successfully, but you think arming them is a good idea.
