Later that same year, on May 4, the shooting of four students at Kent State protesting against the United States' invasion of Cambodia led directly to the student strike of 1970, a nationwide protest by students on college campuses against US involvement in Vietnam, including at Syracuse. Early protests on campus led to firebombing and window-breaking, but Corbally's decision to cancel classes and allow the students to protest without police or administration interference arguably resulted in more moderate protests than at other colleges.
