Vlad at the Glass Bead Collective let us know about another video taken during Saturday night's Pandamonium in Williamsburg, where a roving street party (with a panda theme) was deemed too much by police, who tried to clamp down on festivities.
He writes "the basic story here is that after the panda party was broken up, people started assembling on street corners and chanting," which is when the clash started to become more aggressive and violent: "They arrested a young man pictured in the video here by just pulling him out of the crowd, and as far as i heard charged him with inciting a riot as well as resisting arrest." By the way, inciting a riot can be a felony charge.
Another video, taken by the camerawoman, will be released later. It's apparently very shaky, because she was tackled, too. When we called the police to get some more details, there was apparently no "sheet" about the incident. Mysterious!
