This is the point I have tried to make several times but our resident, dead shot, walmart camo wearing badazzes all think they would be cool under pressure and wipe the shooter out in seconds. So I guess it is safe to say, none of those right wing badazzes are on that police force ! After all the good guy with a gun theory being spewed........... well they stayed outside and waited for others............hmmmmCorrect.
Fortunately (or unfortunately--take your pick), nobody really knows how they are going to react when TSHTF. We don't have that many instances where we can battle test folks, thankfully.
Maybe we should have more real-life drills. Because whatever we end up doing with guns (likely nothing), we're going to have another scenario like this where the police are going to be expected to rush into a situation where everyone else is running out...and risk life and limb. I'm not saying "stage" a make-believe school shooting. But have something where TSHTF and see who is ready to roll and who isn't.
