Metropolitan Police Department of the District of Columbia
The Metropolitan Police Department of the District of Columbia, also known as the DC Police, DCPD, MPD, and MPDC is the municipalpolice force for Washington, D.C. It is one of the ten largest police forces within the United States.
Upon the establishment of the District of Columbia, the states of Maryland and Virginia appointed constables to patrol the city. In 1802, the city was given police primacy and appointed a Captain of the Watch and 15 watchmen. The modern-day Metropolitan Police Department was officially formed on August 6, 1861 in accordance with the personal wishes of PresidentAbraham Lincoln, who had taken a personal interest in the establishment of regular police for the nation's capital.
The department's duties include the provision of police services to the city and its inhabitants and to supplement the various Uniformed Federal Law Enforcement agencies (primarily U.S.Secret Service, U.S. Park Police, FBI Police, and U.S. Capitol Police) in the city, with whom the department exercises concurrent jurisdiction. Additionally, due to its location within an independent federal city, the department must exercise the standard functions of a local police force and also handle certain activities normally considered within the domain of a county police or state police agency such as a sex offender registry.
