Yeah I'm more just wondering is it possible/how hard is it to blast through a deadbolt on a metal door/frame with a shotgun? FWIW I'm not trying to condone the actions (or lack thereof) of the officers, I'm just curious (should I ever be in the same situation).
Bro, if you are ever in that same situation, you act. Our job is to save lives (especially kids). Head to the sound of gunfire and neutralize the threat. I think I still have some powerpoints and training materials, IM me if you're interested.
