For all incidents occurring on the St. Mary's College of Maryland campus and/or the property of Historic St. Mary's City, the Department of Public Safety will provide the primary response. While the Department of Public Safety serves as the proprietary agency when dealing with on-campus incidents, the St. Mary's County Sheriff's Office will have jurisdiction of all criminal actions as described in the "Memorandum of Understanding" between the Sheriff's Office and the College.

Officers may additionally request state or other law enforcement to respond for incidents in which a law enforcement presence is needed. This includes, but is not limited to the following types of incidents: any Part I or Part II crimes; large crowds; acts of physical violence; suspected operation of a motor vehicle while under the influence of alcohol or drugs; motor vehicle accidents involving death, injury, property damage; theft of personal property; drug offenses; death or serious injury of any person on campus; or any other incident of a serious nature.

Officers, during the normal course of their duties, may be requested to assist state or local law enforcement during activities on or contiguous to the campus. Assistance in off-campus incidents is to be rendered but will be limited to: observing the officer in his/her duties to assure officer safety; escorting an officer to locate a subject on or near campus; assisting an officer whose life or safety is in imminent danger; providing traffic direction; or other such services as requested as long as those services do not exceed the limits of the Public Safety Officer's scope of authority.
