From the Lawrence Daily Journal-World for May 12, 1972:
Anti-war protesters were still making their presence felt at Kansas University. A group of demonstrators had taken part in a four-mile march on and around the campus overnight, causing some damage and occasionally disrupting traffic. Twenty-seven arrests had occurred after the group had refused to heed Kansas Atty. Gen. Vern Miller's request to clear Jayhawk Boulevard at the traffic control station at 13th Street. Some protesters had caused damage at the Military Science building by heaving a vacuum cleaner through the glass-paned office door of Capt. Joseph Marzluff, Navy ROTC leader at KU. Chancellor Laurence Chalmers had canceled plans to read an anti-war petition at a rally scheduled for noon today, saying, "The students, faculty and staff of KU deplore the disruption of what was intended to be a peaceful demonstration.... I can't affiliate myself with the events of last night."
