Peace signs on mortar boards are okay, if lame. And, if they had tried to organize something along the lines of "protest the war by pulling your knees up to your chin and swiveling around in your seat till your back is to the President but yet you're not in anyone else's way", I suppose I wouldn't have a thing to complain about.
Annie, did you here anything about protesters being ejected from the ceremony, and did your friend mention whether they were students or audience members?
Bush was invited to speak at the Ohio State commencement by representatives of the graduating class. But immediately before class members filed into the giant football stadium, an announcer instructed the crowd that all the university's speakers deserve to be treated with respect and that anyone demonstrating or heckling could be subject to expulsion and arrest.
