Damn this is right next to me
Like, the city directly adjacent to where I live
like did you think it was a good idea to try and 'threaten' the cop?
If you're carrying a firearm, you're supposed to inform the officer. Because if you don't, and they find out themselves, the reaction can be worse.
That said, I don't know the situation, because the only information available is the video after the fact, but it's possible that the guy worded what he said very badly.
