While this could be true, it also means that if they are determined to rob this place YOU will be the first one shot....
Ummmm.... not so sure about that. Guy sees you, maybe so. But if you're "somewhere in the store", he'd have to go looking for you, waving his gun around in case he finds you, just to eliminate the OC threat. The guy would also have to see you go in, and follow you specifically to the exclusion of any other CC or OC carriers in the place. Doesn't make a lot of sense. If he's gonna rob the place, and he sees you OC going in, I bet he's gonna find a less risky place to rob rather than try to catch you unawares. But that also means he's been sitting at the curb a while, which is loitering and he's trying to not draw attention to himself.
Sure - guy goes into rob a bank he'll try to neutralize the bank guard first, if there is one. But for him to hunt down the OC guys maybe also in there, not so sure. Whatever he's doing, he's gonna want to be quick and get out of there.
If he's whacko, all bets are off. He is either targeting a specific group (bullies, teachers, etc) or he's gonna be indiscriminate and want to kill 'em all.
LEOs - please weigh in on this - am I off base or not?
