Michigan's Law Enforcement Information Network (LEIN) is a statewide computerized information system that enables participating law enforcement agencies to access and/or modify stored information. LEIN includes data bases containing sensitive criminal and law enforcement information accessible by remote terminals throughout the State. The LEIN data files contain a computerized index of documented criminal justice information concerning crimes and criminals of statewide, as well as national, interest. LEIN provides access to the National Law Enforcement Telecommunications System (NLETS), the National Crime Information Center (NCIC), and various state data bases.
