The Naval Criminal Investigative Service (NCIS), along with our federal, tribal, state, county and local law enforcement partners, launched the Law Enforcement Information Exchange (LInX) initiative in 2003.  LInX is designed to enhance information sharing between participating law enforcement agencies in areas of strategic importance to the Department of the Navy.  LInX provides member agencies with secure access to regional crime and incident data and the tools needed to process it, enabling investigators to search across jurisdictional boundaries to help prevent, stop and solve crimes and share that information.  Ownership and control of the data always remains with the agency that provided it.   

LInX is organized regionally, as depicted in the map above, with each region having its own Governance Board. Each member agency has one vote on the Governance Board which is responsible for establishing its own LInX rules, policies and procedures.  There are currently thirteen (13) geographical regions, one (1) federal region, and one (1) region consisting of the law enforcement agencies of the Department of Defense known as the Law Enforcement Defense Data Exchange (D-DEx).  NCIS provides program management for both LInX as a whole and for the D-DEx region.  LInX contains data from nearly 1300 law enforcement agencies who share more than 680 million incident reports, 530 million narrative reports, and 64 million mug shots. Additionally, LInX users can access thousands of data streams from a number of partner systems such as the Federal Bureau of Investigation's (FBI) National Data Exchange (N-DEx) and the Department of Homeland Security's TECS and ENFORCE. 

 LInX enjoys the support of agencies as large as the Los Angeles and Chicago Police Departments and as small as the 6 or 7 officer police departments located outside the gates of Navy facilities across the country. Law enforcement professionals with decades of experience describe LInX as the best investigative tool they have seen in their careers. It is a force multiplier that helps law enforcement personnel resolve all types of criminal cases.
