Dude there were definitely armed shoppers there. Everyone wants to be billy bad ass and strap on a gun but no one wants to rely on their (severe lack of) capability. Mix that with a bit of “fuck this I’m (and my family are) out of here. If something pops up between me and the exit, I’ll go to work. Otherwise, fuck this.”
I don’t give a fuck about anyone but my family (or myself if I’m alone) while out and about. Get in my way as I exit, I’ll go to work. Otherwise, I’m not LE and I’m not getting shot by another shopper or LE by trying to be hero.
I'm almost there with you. If my family is with me, they are my protectees. They will be hustled the fuck out of danger forthwith and anyone stepping in the way is getting decked or worse.
If I'm alone, that's a different story. Five years ago I would have told you that I would unass the area ASAP since the fight isn't with me. Now, today, I see things a little differently.
