Ok, here's the thing...

1. The guy bitches about the time it took the cops to get there...

This pisses the cops off and the situation goes down hill from there.

You have just as much right to bitch to a cop about their response time as you have right to bitch at the manager of a McDonalds...

The cop has no right...0 right to demand the guy stop bitching about the response time.

2. As for the guy being asked to extinguish his cigarette... No problem there, It's a common courtesy thing and technically the officer could claim assault if the guy's smoke came near the officer.

3. As for the "in your face"... It is difficult to tell. The officer has learned to use the camera to his advantage as well as to narrate the scene for future reference.

4. The officer should be not only fired but charged with assault AND battery.
