As I said, the rider may very well have done something we didn't get to see.
The police report simply confirms my suspicions
I don’t know the layout, but is it possible that he was trying to be a “corker” (see the Wikipedia article on Critical Mass) and the cop stopped him?
If he did something then the cop would have put that in his report instead of lying and saying the guy tried to run him down, leaving out his tackle of the biker.
Except that in the beginning of the video, it is clear that all traffic is completely stopped, while the annoying bicyclists pass.
Plus, the cop is proven to be a liar in every claim he makes that can be confirmed or disproved by the events on the video.
Why do you bend over backwards to believe the cop, when he's proven to be a liar?
