You are obviously ignorant of the facts. Those untrained teachers, without anyone having to ask them, did exactly what you said we could never ask them to do; only they did it UNARMED and gave their lives in the process without stopping the killer.
No doubt, wtmoore1, you are projecting your own cowardice upon our teachers. Given the profoundly heroric actions by unarmed teachers in Newton, you comments are disgusting.
What is unwise, and unfair, is to ask teachers to confront gunmen without being armed themselves.
