Hey, JoshB, Great Responses!
Personally, I would have pulled out my pistol, "suggest" that he slowly place his on the counter and then call the cops.
They would have arrested you when they got there, smart move. Actually, based on your posts here, I think you should do this next time.
Why is everyone saying that we should leave the situation alone and call the police?
Because we aren't cops, and he didn't do anything patently illegal anyway. Hard to say he was brandishing if you're the only one that saw it.
What is so wrong with the idea of someone exercising the individual right to defend himself and others granted by the Constitution?
Missed that part of the Constitution, could you quote it?
While calling the cops is a good idea, they can't help you when this guy does pull out his pistol and starts shooting others.
Yeah, but he didn't do that. And unless you are psychic, you don't know he would have. He didn't. Foolish assumption.
Why is Big Brother the only one who can intervene when someone does not act responsibly with a firearm?
Because that's the law and you aren't a cop.
I don't know if you have a carry permit, or if you carry, but I doubt you will be allowed to for much longer if that's how you think you should be acting. It's a carry permit, not a badge. Your reactions to this would have been just as irresponsible as the party in question.
