The U.S. Department of Justice established the Law Enforcement Information Sharing Program (LEISP) to achieve the Department’s vision of creating relationships and methods for routinely and securely sharing criminal information across jurisdictional boundaries. It mandates the kind of wide-reaching information sharing program necessary to deter terrorism and to increase the amount of information available for the investigation and prosecution of criminal activity. The LEISP was designed in response to IRTPA requirements and U.S. Attorney General mandates for sharing DOJ data with the ISE.
The LEISP requires all DOJ components to share law enforcement information — unclassified and classified — with all law enforcement partners, with the exception of certain categories of information designated by the Deputy Attorney General (DAG). It minimizes barriers to information sharing, provides a single point of contact for DOJ information, and provides a foundation for information sharing among law enforcement at the federal, state, local, and tribal levels.
To advance and support the LEISP strategy, the DAG directed the FBI and other DOJ components to participate in regional and national law enforcement information sharing initiatives. Accordingly, the FBI has implemented information sharing technologies which support this directive and which operationalize the FBI’s National Information Sharing Strategy. The Law Enforcement National Data Exchange (N-DEX) program is a national information sharing system designed for use by all federal, state, local, and tribal law enforcement agencies. N-DEX allows agencies to search and analyze data using powerful automated capabilities.
