I watched the vid frame by frame. Something's not right. The start, his left leg is the one apparently under pressure. The next few frames, it now becomes his right leg under pressure and he's wiggling the left. Seems kinda ridiculous to me, but eh.
Feels a little exaggerated, I would not base it on this video alone judging by the 10+ other people recording with a better picture.
I don't doubt he was in some sort of pain from the cuffing, don't think anyone ever enjoys that except the police who do it.
Here's what I think happened:
First, I don't think this was staged. HOWEVER, I do think protesters, or anyone sympathetic to the protesters are looking for every reason and opportunity they can to make the police look bad in front of cameras and the world. They have very good reason for this, as the police have, on many occasions during this entire protest, used excessive and intimidating force. They are not conducting themselves appropriately (nothing new for NYPD).
The man in question (an observer--not a protester) was knocked to the ground. We don't know how he was knocked down. No video available (yet) shows this. So, he's on the ground kicking his legs around. Neither leg is pinned beneath the scooter. This is clear. I agree, his behavior seems dramatic and overdone. The cop on the scooter is stopped at this moment.
As the throng of cameramen and police crowd around to see what is going on, the cop on the scooter drives forward a few feet. This is very hard to catch, but if you pay attention, you will see that he moves forward. At this point, the rear wheel of the bike is on top of the man's ankle. This is clear. His leg is not "wedged." The bike is completely on top of his ankle, and the man is pain. What I think happened here is an accident. I think the cop was simply trying to get out of the way as the man was causing a scene. The man, in his attempt to be dramatic, got his ankle pinned by the rear wheel. He wasn't expecting that. Oh damn, real pain! shit!
At this point, the crowd becomes pissed off. They see the cop drive on top of the man's leg and the mood shifts to something more serious. The cops, sensing this sudden change, become very hostile. Notice how they start pushing everyone away and clearing the scene? That is standard typical cop behavior when they sense anger from a crowd.
Next, another group of cops, thinking that the man has been faking all of this to incite the crowd, close in on him in a very aggressive and excessive manner. One cop clearly raises his baton in order to strike and brings it down to a point that is inconclusive. Why would he even attempt to strike the man in the first place? That makes no sense when he was just lying on the ground pinned by the scooter.
There are a lot of unanswered questions here. Both parties are most likely at fault. However, I hold police officers at a higher standard to conduct themselves appropriately than the general population. That is their job. They have been entrusted with upholding the law and keeping peace. You do not keep peace by provoking and inciting the anger of a protesting crowd.
The slogan "question authority" came out of the anti-war movement of the 60s. It does not mean to attack authority or to disregard authority. It simply means to question authority and the possibility that authority is not always right.
What I see on this thread are several people who "question the people" and start from the vantage point that the police have done nothing wrong and that it is the people, exercising their American right, that should be held to higher scrutiny than authority.
That is disturbing.
