Presumably moments before last night's rally / dance party flash mob at UC Berkeley, sparked by cranky tuition-hike protesters, gained momentum, this student protester was swallowed up by riot police. According to the this video's maker, Narukami, the girl was "taken and arrested by police while she was telling everyone how a police officer punched her in the nose."
Somewhere around 200 people rioted south of campus last night. Check out more images of students who just aren't going to take it anymore.
