“Might teachers with guns, who personally know the kids under attack, react more successfully?”
In Men Under Fire - S.L.A. Marshall - wrote a book on WW2 that analyzed why some men fight and other men simply hide in battle.
The primary difference was alligance to their fellow soldiers. Makes a compelling point about those “who know the kids personally.”
Like the coach that ran towards the shooting and died trying to protect “his” kids. (I’m not sure if he saved them or not).
