Funny, I just got done watching this and I will agree- WOW.
I think what pissed the cop off so much is it dawned on him how stupid he and his partner had been and how close to getting capped had the CCW holder had ill intent.
I am not a LEO but common sense would dictate they secure the occupants before searching the vehicle.
And the statements made to the CCW holder once he is detained by the cop should cost him his job.
