I’m betting the cops didn’t “see” anything.
Most CCW holders understand that “concealed” means CONCEALED!
This guy has been marked for harrassment.
Don’t ask what I’d do in his situation....
I suspect that the police recognized him from the recording incident, actively looked for a "bulge" and then decided to beat him.
In a state with Shall Issue CCW, the presumption should be that somebody carrying concealed has a permit, and does not excuse this conduct.
