The Prince George's County Sheriff's Office (PGSO), officially the Office of the Sheriff, Prince George's County, provides law enforcement services in Prince George's County, Maryland in the United States. Its headquarters are located in Upper Marlboro, near the Depot Pond. The sheriff is the chief law enforcement officer of Prince George's County and is elected every four years. There are no term limits for the sheriff.Created in 1696, the traditional duties of the sheriff are keeper of the public peace and the enforcement arm of the county court, analogous to the U.S. Marshals Service. The PGSO has a relatively long history compared to other police departments and sheriff's offices in Maryland. The PGSO was involved with events that occurred during the burning of Washington and affected the writing of "The Star-Spangled Banner". Prior to 1931, the PGSO was the sole law enforcement organization of the county.Today, the duties of the sheriff include law enforcement services of the two county courthouses and surrounding property, service of court-ordered warrants, writs, protective orders, and other injunctions, and limited patrol responsibility with the County Police. The Domestic Violence Unit has expanded its role in the county to include responding to calls for service that are domestic-related. The creation of the School Resource Deputy division has placed a deputy sheriff at all of the local high schools, replacing the County Police. All other law enforcement services of the county are provided by multiple agencies but mostly left to the separate Prince George's County Police Department (PGPD), though some responsibilities are shared by both agencies. The PGSO, like most other county-level law enforcement agencies in the United States, is a progressive agency with an array of services, from the Specialized Services Team (dealing with high-risk arrest warrants and barricaded situations) to community services aiding the county's residents in safety education. The PGSO was accredited for the first time by the Commission on Accreditation for Law Enforcement Agencies, Inc. (CALEA) in 2018.
