What this NYPD Officer does to an Uber driver might leave you enraged

From the about the video on the Youtube Excerpt

“Police abuse of Uber driver in New York City. In an unmarked car, the policeman was allegedly attempting to park without using his blinker at a green light. (His reverse lights weren’t on. Likely double parked without hazards on.) The Uber driver pulled around and gestured that he should use his blinker, casually and non-offensively, and kept driving us. The policeman quickly pulls up behind us and this is what happens.
This occurred just before 2pm on the West side of Manhattan, in NYPD 6th Precinct, on March 30th, 2015, near Little West 12th Street. The officer did not identify himself, but he had a New York license plate: GSS 8891.

The officer was later identified as Detective Patrick Cherry, at the time a member of the FBI’s Joint Terrorism Task Force.

As of April 1st, 2015, NYPD Commissioner Bratton has announced his transfer off the Task Force, saying “All good cops know that the officer just made their jobs a little bit harder. … Anger like that is unacceptable in any encounter. Discourtesy like that and language like that is unacceptable. That officer’s behavior reflected poorly on everyone who wears that uniform.””
