See why arming teachers is a stupid idea , so many possible variables that could be negative. First teacher with gun is the shooter causing the deaths, Second kid gets hold of the gun accident happens killing teacher or student, Third teacher is a pervert uses gun to force student into sex, armed teacher shot by police by accident, so many way this thing could go sideways.
One way has been proven true already teacher in Georgia did shoot a gun or it went off accidental or whatever lucky no one was shot. Time to see the big picture use your brain say wait a minute think this out fully. Don't buy NRA first response they are trying to sell more guns
