You seem to think there are still one room schoolhouses, like when you were a child.<quoted text>
In a school environment, the security would best be provided by someone analogous to an air marshal, an armed teacher or staff member whose identity was not public. Cost would be minimal because this person would have a regular job. A visible uniformed cop would just be taken out first by a determined killer.
So this armed guard can be in all areas of the school at once??
Did you see how big the school in CT was?? Or Va Tech??
You talk thru your azz, and pretend it's thoughtful dialogue.
It's a right wing disease.
