Freedom of Speech vs Disrupting the Peace at University of California Irvine

This blog is a response to this article.
At University of California Irvine while the Israeli ambassador on campus was giving a speech, many Muslim students stood up, interrupted his speech, and shouted over him attacking his viewpoints. This video was taken during the speech and shows just what happened. The students were arrested, prosecuted, and convicted for "violating a law against disrupting public meetings." The students argued they were within their first amendment rights of free speech and they were convicted solely because they were Muslims. The University asked the District Attorney to drop the changes claiming the University had already punished them. The group Jewish Voice for Peace supported the Universities request to drop the charges.
I have two responses to this article. First, I do not agree with the students' arguments that they were exercising their freedom of speech and did not do anything wrong. Freedom of speech does not give you the right to say what you want when you want it. They have the right to their opinion and can express it freely without having to disrupt a public speech. What they did was not only disturbing the peace, but it clearly interfered with the learning process on campus. They can bring in their own speakers, or even get a sanctioned time in a lecture hall to express their ideas where no one would have the right to interrupt them.
My second response is that I do agree with the idea that this was a trial that should not have taken place. They violated a school rule against disrupting public meetings, and the school was right to punish them. However, the fact that they were convicted in court I do believe was somewhat bias to their religion. In court I think it was more about what they said, then the idea that they said something. What they did was wrong, but a misdemeanor might be taking it too far. At most give them a warning. If they did not learn from the schools punishment and continue to engage in this behavior, the school can expel them. Because what they did was not a serious danger to society, there's no need to take it any farther. Especially when there's the possibility of a bias jury.
