# LInX **Domain:** Austin Research / Surveillance **Doc Type:** Research entity **Source basis:** Supplied essay and the specifically identified records; verification scope is recorded in [[wiki/Austin Surveillance Evidence Ledger|the evidence ledger]]. **LInX**, the Law Enforcement Information Exchange, is a law-enforcement sharing system sponsored by the Naval Criminal Investigative Service. NCIS describes participation by local, county, state, tribal, federal, and military agencies, with cross-jurisdictional searching, relationship analysis, and mapping. Military law-enforcement data also enters through D-DEx. DHS’s historical LEIS briefing lists **LInX Northwest and National Capital Region LInX as existing MOU partners**, while placing other regional LInX arrangements in a discussion category. Regional names and agreement states therefore matter; the presence of one LInX node does not date every other node’s integration. NCIS’s contemporary description explicitly identifies interoperability with the FBI’s [[wiki/National Data Exchange|N-DEx]]. That is a later, independently documented interface and should not be backdated from today’s system to the briefing’s FY2010 plans. Within the Austin cluster, LInX makes the national and military-law-enforcement breadth of LEAP’s federal peer environment concrete. The supported relationship is LEAP and specified LInX nodes sharing the DHS agreement layer; a direct Austin-to-every-LInX data route requires its own evidence. ## Connected entries [[wiki/DHS Law Enforcement Information Sharing Service|DHS Law Enforcement Information Sharing Service]] · [[wiki/Law Enforcement Analysis Portal|Law Enforcement Analysis Portal]] · [[wiki/National Data Exchange|National Data Exchange]] · [[wiki/Interlocal Information Sharing|Interlocal Information Sharing]] ## Sources and corpus context - [[research/The Austin Surveillance Field|The Austin Surveillance Field]] - [DHS — Law Enforcement Information Sharing Service briefing, slides 4–16; existing MOUs on slide 15](https://info.publicintelligence.net/DHS-LEISS.pdf) - [NCIS — LInX/D-DEx, sponsorship, participation, and N-DEx interoperability](https://www.ncis.navy.mil/About-NCIS/Mission/Partnership-Initiatives/LInX-D-DEx/) **Cluster:** [[wiki/Austin Surveillance Field|Austin Surveillance Field]] · [[wiki/Austin Executable Loop|Austin Executable Loop]] · [[wiki/Austin Surveillance Evidence Ledger|Austin Surveillance Evidence Ledger]]
