Arizona State University President Michael Crow vowed Thursday that swift and substantial action would be taken against four fraternities in general and the executive vice president of the student body in particular for their roles in a pornographic video shot on campus last fall. Brian Buck, a 23-year-old business and psychology senior, is one of dozens of male ASU students who appear in Shane's World #29: Frat Row Scavenger Hunt 3. In the professionally produced video, a nude Buck is seen showering with two adult-film actresses and sitting in a limousine next to an actor engaged in a sex act.
