Police beat an SF man for riding his bicycle on the sidewalk

Although the video does not show the entire incident, it is obvious that the witnesses and the victim are reacting in the video to something that should not be happening. What is known from witnesses is that 20-year-old D'Paris Williams was riding his bike on the sidewalk of a San Francisco apartment complex. The police try to tell him to get off of his bike. His sister, Christina Williams, 21, said that he was bringing his bicycle into his apartment building and did not hear the police because he was listening to music. When he did not comply with the police, they tried to detain him and a struggle ensued. If you watch the video, you can see his face is bloody from whatever altercation occurred before the camera was turned on. There are surveillance cameras and footage being reviewed as evidence and has not been shown to the public. Hopefully the public gets to review the footage from the scene and the victim can move forward with a criminal or civil case against the abuse of the police officers. http://blog.sfgate.com/crime/2013/11/18/video-prompts-cries-of-s-f-police-brutality/
