The Michigan State Police (MSP) is the state police agency for the U.S. state of Michigan. The MSP is a full-service law enforcement agency, with its sworn members having full police powers statewide. The department was founded in 1917 as a wartime constabulary (originally named the Michigan State Troops Permanent Force) and eventually evolved into the modern agency that it is today. The department's entry-level members are called "Recruits", who eventually earn the title of "Trooper". Its headquarters is in Dimondale, Michigan. History The Michigan Department of State Police began as a temporary, wartime emergency force for the purpose of domestic security during World War I. On April 19, 1917, Governor Albert Sleeper created the Michigan State Troops Permanent Force, also known as the Michigan State Constabulary. With Colonel Roy C. Vandercook as the first commanding officer, this new force consisted of five Troops of mounted, dismounted and motorized units, totaling 300 men. With Michigan going "dry", enacting state liquor prohibition effective May 1, 1918, and Ohio "wet", the force was soon stationed in Monroe County by 1918 due to the smuggling going on. On March 26, 1919, Public Act 26 reorganized the Constabulary as the permanent, peacetime Michigan State Police. Throughout the history of the department, its members have participated in many important events. Some of the earliest duties of the department involved its troopers being dispatched on horseback to the iron-rich regions of the state's Upper Peninsula to guarantee the mining and distribution of the vital ore. A Bureau of Investigation and Identification was started by Capt. Ira H. Marmon opened in 1919 at the East Lansing Headquarters with an old shoebox fingerprint records file previous kept under his barracks cot next to his desk. In the mid-1970s Michigan Governor William Milliken gave the Michigan State Police a permanent presence on Detroit area freeways which culminated in the opening of the Detroit Freeway post in Downtown Detroit. This action was taken after a rash of crimes on the Detroit area freeway system and local law enforcement had limited resources in doing expressway patrols on a regular basis. MSP troopers were deployed in Benton Harbor in the summer of 2003 to quell civil unrest that was occurring within that city. Troopers were also deployed to Louisiana in September 2005 following Hurricane Katrina to assist local authorities with search and rescue, law enforcement, and humanitarian efforts in the devastated city
