Last night's Sacramento Critical Mass ride started out beautifully from Cesar Chavez park at about 5:30 with about 40 riders. The ride headed down a main downtown street, and then zig zagged around the city for about a half hour before the police began to make arrests. In the end, four riders would be arrested, many while waiting for traffic lights, and generally obeying all traffic stops and rules. One rider, according to a report, was grabbed by the arm, his wrist was forcibly twisted into "pain compliance holds," to which the rider responded by repeatedly asking what the officer was doing. The officer stood there, twisting his wrist back and forth, obviously not trying to do anything except cause pain and injury. The situation escalated further when several more officers ran over and tackled the rider to the ground. There were 4-5 officers pinning the rider to the ground, some kicking, others twisting his wrists, and yet another putting on handcuffs. Muffled screams of "YOU ARE HURTING ME," and "PLEASE STOP," could be heard from underneath the pile of officers. Read full report here.
