How should kids react in a school shooting?

[Beren Son Of Barahi]

AFAIK most of these events happen with students that have been suspended/expelled;it would make sense to control who can come in and out of a school; swipe cards/access control would be a much better way of stopping someone getting into the school then teaching kids to charge the trenchesgunmen.

I think this sort of thinking is all cartage in front of the horse type of problem solving. stop the school shootings before they happen or restrict the movement within the school.

i would of thought that it might be better to evacuate when possible instead of staying put.
