Ryan Quinn at Inside Higher Ed:

A conservative Princeton University professor tried to give a speech this month at Washington College centering on the need for campus free speech. Students disrupted his talk and succeeded in ending it. It was another example of what are often called student shoutdowns or “heckler’s vetoes”—though the meaning of that phrase is contested—disrupting conservative speakers. Perhaps most prominently this year, in March, Stanford University students disrupted a talk by Judge Kyle Duncan of the U.S. Court of Appeals for the Fifth Circuit. This month’s Washington College incident, first reported by The Star Democrat and later by The Chronicle of Higher Education, featured Robert George, who didn’t respond to Inside Higher Ed’s requests for comment Tuesday. He’s the McCormick Professor of Jurisprudence at Princeton and directs Princeton’s James Madison Program in American Ideals and Institutions, which recently released a new set of proposed academic freedom and free speech principles.
