Massachusetts State Police

The Massachusetts State Police (MSP) is an agency of the Commonwealth of Massachusetts' Executive Office of Public Safety and Security, responsible for law enforcement and vehicle regulation across the state. As of 2022, it has 2,067 sworn troopers and 611 civilian support staff for a total of 2,678 personnel, making it the largest law enforcement agency in New England. The MSP is headed by Interim Lieutenant Colonel Jack Mawn. History The MSP was established by Massachusetts state governor John A. Andrew when he signed a law creating the State Constabulary on May 16, 1865. This legislative act to "establish a State Police Force", founded the first statewide enforcement agency in the nation. The first leader of the State Police was William Sterling King, an American officer in the Union Army during the American Civil War. The agency remained small and rather informal until 1921, when the MSP was enlarged to comprise 50 officers stationed in barracks across the state with the primary mission of providing law enforcement to rural areas underserved by existing local police agencies. This law enforcement mission was performed by the trooper on horseback, usually, and in motor cars in areas with upgraded roads. The MSP enlarged its mission to handle primary vehicular regulation on the Commonwealth's interstate and limited-access highways after their development mid-century; during this period, it also established a presence in protecting Logan International Airport. For much of the twentieth century, the MSP was organized along military lines with a heavy emphasis on the role of the barracks, spartan working conditions, and a uniformity in appearance and internal culture. Until recently, the MSP maintained one of the strictest regimens for physical size requirements for applicants. Efforts are being made presently to render the department more racially diverse, as well as more inclusive of women and LGBT troopers. The history of the agency is preserved at the Massachusetts State Police Museum and Learning Center in Whitinsville. The museum was made possible by private donations from MSP troopers and employees. The museum, originally intended to be located at the site of the former Troop C2 barracks, was relocated to a building in Whitinsville after a fire damaged a portion of the old barracks building in 2017. Exhibits at the museum include:
