This is the video of police officers repeatedly tasering Mostafa Tabatabainejad in the UCLA library on Tuesday night. The story (so far) is that he didn't have library ID and refused to leave, the police arrived, he started to leave, they grabbed him, he told them to let go of him, and they tased him. That's when the video starts.
It's horrifying. It really makes me physically ill. You probably don't want to watch it.
UPDATE: This has agitated me enough to finish off "Bethsheba 2006," a song about people who become collateral damage.
