This is nuts.
But wait, it gets worse. Initially the cylist was arrested and charged with assaulting a police officer. The police officer said in an affidavit that the cyclist deliberately ran into him (though you can clearly see the cyclist trying to go around him). The cyclist was held in custody for 26 hours.
At least the cop's father is proud of him: "These people are taking over the streets and impeding the flow of traffic. Then you gotta do what you gotta do," he said, not having viewed the video.
I must say: hooray for citizen journalism!
Disclaimer: it is possible the cyclist did something else really really bad earlier and the cops were specifically looking for him. Like maybe he was a terrorist with a ticking time bomb. It better have been that bad because a hit like that could have killed the guy (helmetless onto pavement!)
