Mostafa Tabatabainejad was tazered by university police, after he failed to exit the university library quickly enough when he failed to produce the ID that is required of all students using the library after 11. He was tasered once when he didn't get out quickly enough, and then repeatedly after that for failing to stand up after being tazered the first time. Other students who asked the police for their names and badge numbers where threatened with tazering.
The whole incident is was caught on camera phone, and accompanies this article.
