I'm opposed to arming teachers. Kids nowadays have zero respect for authority, just take a walk in an inner school and you will see my point. If a teacher is assaulted, threatened or challenged and utilize that firearm we have just created another mess. My brother is a teacher in the inner city and he is always being challenged by his students and he is a big boy! David is correct, locking the doors and keeping them locked is the way to go. If there are arm guards in every school, who is paying for it, unintended consequences and for how long? Then you have to look at training, psyche evaluations etc... We are doing what, Americans always do, try to solve a problem by creating another problem. We seem to never learn our lesson.
