The TRC has worked with the Los Angeles Terrorism Early Warning ( TEW ) Group since 1997 . The TRC and Los Angeles County Sheriff 's Department ( LASD ) submitted a grant application to the Memorial Institute for the Prevention of Terrorism to expand the Terrorism Early Warning Group concept to six high threat cities in the U.S . The Terrorism Early Warning Group concept fulfills the intelligence requirements outlined in Homeland Security Directive 8 : Interim National Preparedness Goal . After the September 11 attacks in 2001 and the formation of the Department of Homeland Security , the Terrorism Early Warning Group program was migrated to DHS and expanded to cover 56 high threat urban areas . The TRC worked with these 56 cities to develop early warning and intelligence centers that became the precursor the national Fusion Center network
