MrPaul, I agree with you an David. However, could you clarify "perimeter security system". I'm still in Uncle Sam's gang (Army) and that sounds like a patrol base etc...to me. Again, the doors should be locked in the classroom. To me this is this makes sense. Teachers are not there to defend these kids, their purpose is to educate them. Our education system, which has been thoroughly infiltrated by radicals, is bad enough. The last thing we need is teachers more focus on security than doing what they were hired to do in the first place. In my view, the NRA is wrong on this one. If anyone is to be armed in a school let it be the principal.
