So wait a minute, to get this straight:
Guy complains to cop that they took forever to get here. While talking he takes a casual step in the direction of the cop (not even half a fucking step). The cop also goes a step towards him, and punches him in the face. After humiliating the guy with fuckwhat he insists that the guy stepped up and got in the face of a police officer. Several times. After two minutes and several forced apologies the guy asks why THE COP stepped up to HIM. And instead to sticking with his bullshit excuse the cop says "cause I wanted to talk to you and not have to yell", contradicting his own fucking story and lying. BUT he says that the guys story about the cop on the phone telling him to fuck off or something HAS GOT to be a lie, because they are all police officers and therefore PROFESSIONALS?
Fuck this cop, he should lose his fucking job asap, he obviously is NOT behaving professional, he is too fucking STUPID to stick with his own flimsy view of events while this is all videotaped by himself, wrong career choice fuckhead.
As to the guy being a "douche", well, so what? I'd be pissed if the police took 45 minutes to get to me, I'd pussy out too if a cop just fucking knocked my head off without any reason whatsoever and put me in cuffs. That changes nothing about the abusive dick in uniform
