The Cornell University Police Department is an internationally accredited organization that operates 24 hours a day, 365 days a year, from its headquarters in Barton Hall. The department has 55 members, 52 of them sworn officers who patrol the campus on foot, in vehicles, on bicycles, and with explosive detection K-9s. The mission of Cornell Police is to protect lives and property, maintain order, prevent crimes, receive and investigate reports of crimes, and provide other law-enforcement services.  The department is responsive to the special needs of Cornell’s large and diverse community—a community of people who come from across the United States and the world to study and work at Cornell.
