The Washington Post has more on the University of Florida Tasering incident:

There are some important things worth noting BEFORE you watch the video: 1.) Before Meyer is tasered, audience members can be heard applauding the police as they move him away from the microphone. Kerry staffers we spoke with say University of Florida officials told them the student has caused a fuss at similar events before, thus the clapping from members of the audience. 2.) Sen. Kerry was in town giving a lecture on foreign policy. The event was scheduled to last one hour, and had already run about 90 minutes by the time Meyer got to the microphone, according to a Kerry staffer. 3.) In some versions of the video, you can clearly hear Sen. Kerry say he will answer Meyer’s questions. Kerry’s office made it clear he has a policy of answering questions from anyone who asks at these types of events. 4.) Sen. Kerry’s office issued the statement below: “In 37 years of public appearances, through wars, protests and highly emotional events, I have never had a dialogue end this way. I believe I could have handled the situation without interruption, but I do not know what warnings or other exchanges transpired between the young man and the police prior to his barging to the front of the line and their intervention. I asked the police to allow me to answer the question and was in the process of responding when he was taken into custody. I was not aware that a taser was used until after I left the building. I hope that neither the student nor any of the police were injured. I regret enormously that a good healthy discussion was interrupted.”
