As many as 15,000 people participated in actions across Oakland yesterday, with small marches peeling off to protest in front of banks or “occupy” foreclosed homes. There were probably eight to ten times the number of people in the streets of Oakland today as I’d seen during past OWS actions. Police maintained a minimal presence throughout the day. There were a few scattered acts of vandalism — windows were broken at two banks but there was no violence, and the protests were remarkably up-beat throughout the day. But that changed when night fell as the streets of Oakland once again resonated with the sharp cracks of tear gas canisters and “less lethal” projectiles being fired, and flash-bang grenades scattering the crowd.
