I wonder why the cops came in the first place? I heard someone trying to explain it on the video, but you could hardly hear it. Thats amazing that they did that in front of so many people and IMO they were pretty lucky not to have caused a riot especially when threatening others that they would be tazered as well.
Keep in mind these are "UCLA" cops which I dont believe are a part of the LAPD, but im not sure.
Found a news report of the incident on YouTube. In this video, the reporter says the student's name is Mustafa Taba tab-something, which is why he is yelling about the Patriot Act I am assuming. His ethnicity will bode well for him when he decides to sue.
PS - UCLA sucks! Go Trojans!
