From the BBC:
Police in San Francisco have arrested 1,025 people during violence at an anti-war demonstration.
Protesters blocked streets leading from the city’s Oakland Bay Bridge, while small groups of people clashed with police and threw debris. Tens of thousands of people joined demonstrations across the US
I was in Times Square, protesting in the rain till my hands turned blue. There were a few thousand people and it was fairly peaceful despite the HUGE police presence. It was pretty neat taking over the heart of NY City for peace.
