The police were called twice for a domestic dispute by a Karen, as you put it. Maybe it was a garden variety noise complaint. Doesn’t matter, they were called, they didn’t just show up to execute someone. Keep it in context.
As for owning a gun, You don’t know that he was allowed to. Maybe he was a felon, and the cops knew that, based on the readout from the address information. Maybe he was just a guy with no record. Regardless, even though he’s authorized to carry and own, he made a poor decision showing up to the door with a gun when police were knocking and identifying themselves.
I’m as ardent of a 2A person as there is on this board. That’s poor decision making on that guy’s part. I have guns in every room of my house. I usually have one on my person. If the police show up, before I even open the door, I’m announcing that I’m armed and willing to comply with every request made. Then, I’m opening my door slowly and in a very non-threatening manner, I’m keeping the temperature as low as possible. I’ve seen the really ugly side of when principled people antagonize nervous people with guns. It doesn’t work out well for the principled person, ever, and I have **** to live for.
