At a Critical Mass in Hollywood, a rider stopped to record police abusing bicyclists.
At 0:25 a police officer can be seen deliberately kicking hard as a bicyclist goes past, apparently trying to knock him off his bike. After the cameraman shouted, "Oh, oh, oh! What the $%^& was that for?", the police came across the street and tackled the cameraman.
The LAPD is investigating.
