To add: The silent majority of Americans would like to see the outside agitators and spoiled student get their asp kicked of the campus for violating both campus rules and human decency.
Free speech does not include incitement, hate speech, and intimidation. I remember after 9-11 how many from the Jewish Community sat with their Muslim neighbors in their shops to help protect them from morons who indiscriminately attacked Muslims and even Sikhs who they thought were Muslims. No room for these kinds of demonstrations in out society!
