Witnesses are saying that what had been a peaceful protest was suddenly marred when police began attacking the crowd with fists and batons. From the pieces of information drifting in now, it seems that a number of plainclothes officers had been in the crowd, and that some kind of altercation broke out. It's unclear what happened, but according to one witness, the cop began chasing (and possibly grabbing at) a person in the crowd, when he suddenly collapsed. Upon seeing the officer down and not knowing why, the other officers seem to have erupted into violence and attacked the crowd. Four people were arrested and many others suffered injuries. At least one indy videoista was attacked, and had his camera damaged.
Word has it, demonstrators had a moment of silence out of respect for the downed officer when they learned of his condition. So far, I have not heard any indications of police holding a moment of silence to contemplate the injuries caused to the non-violent protesters whom they attacked.
