Well, this link (
Michellemalkin.com) tells a more complete story of the events (as well as including eye-witness testimonies from other students and a video clip where you can here his conversations with the officers before his mic is cut).
It mentions that the student in question, Andrew Meyer, had a habit of making scenes to draw attention to himself... that he had already disrupted the proceeding prior to when the videos circulating begin (hence the two officers standing close to him at the start of the videos), and that he was asked to leave. Did you notice the audience applauding when the officers began attempting to escort him out? The applause wasn't for him, it was for the officers (of course, this same crowd became a little upset when he was screaming and being tasered in the back row). While I'm still unsure as to whether the amount of force used to restrain him was excessive or not... the incident was not spurred by him simply asking a question.
