Hmmmm I do think he over-reacted a little but then you don't see what happened before the start of the video and she was obviously baiting him. He gave her a chance to stop but it seems that she continued (or so we are lead to believe).
Agreed.
I think neither was right, although the girl was more of a douche than the cop.
The cop seemed bothered by something from before the video started. Obviously, since this video was meant to influence opinions to be against the officer, they don't show what happened.
But the whole non verbal communication of the cop, just spend some time looking at his face and neck, says that if the camera hadn't been in his face, the girl would have been blowing bubbles out of her ass. Basically, he's using his command presence wrongly.
The girl on the other hand is the epitome of doucheness. And the simple fact that the "director" (I'm using the term lightly) of the film used the moments later plot twist twice is a clear indicator that the real reason she was carted off is not shown. I'm willing to bet that the older guy, the one who throws in the oh so predictable it's my tax money argument, made her feel like she was supported in what she was doing, which caused here to have a rather flippant attitude.
Me, I'm a revolutionary to the core. But these sort of clowns act like they are socially involved, but in all fairness, all most of them want is to not pay rent, get water and electricity for free (God knows why, most of them don't shower...) and generally just f*ck sh*t up for those who are socially aware and involved. I'm happy to say I've been involved in removing such people from the buildings they've been squatting in a few times in the past.
