Scenario question

So recently I had some guys try to run the classic white van/home theater speaker scam on me. They got pretty mad when I (in kinder words) told them to fuck off. My question is this: there were two of them. Not small guys by any means. If they had gotten out without any visible weapons to confront me, would there be an acceptable time to draw? On one hand there's no weapons but on the other hand two guys just tried to scam you, got mad when you told them no, and are now getting out of their car and coming your way. For all I know their original intentions weren't even to scam me, they could have been trying to get me to meet behind the store or something to rob me. I've just been pondering this scenario and honestly idk what I'd do. It doesn't seem worthy of pulling a gun in public but on the other hand if two guys are trying to beat my ass, I feel like I should be justified in trying to defend myself. via /r/CCW https://ift.tt/2Wp5w42
