Each of the 94 U.S. Attorney's Offices has a LECC comprised of federal, state, and local law enforcement agencies. In districts that contain Indian Country, like Idaho, tribal police departments are also part of the LECC. The goal of the LECC is to improve cooperation and coordination among the various groups, thereby enhancing the overall effectiveness and efficiency of the criminal justice system.
Federal members include the Bureau of Alcohol, Tobacco, Firearms and Explosives, the Drug Enforcement Administration, Federal Bureau of Investigation, Food and Drug Administration, Bureau of Indian Affairs Law Enforcement, Internal Revenue Service - Criminal Investigation Division, Bureau of Immigration and Customs Enforcement - Homeland Security Investigations, the Marshals Service, Postal Inspection Service, Secret Service, Forest Service - Law Enforcement & Investigations, the Fish and Wildlife Service, Bureau of Land Management - Law Enforcement, Customs and Border Protection, Air Force Judge Advocate General, Air Force Office of Special Investigations, Department of Health & Human Services - Office of the Inspector General, Environmental Protection Agency - Criminal Investigation Division, Department of Energy – Office of Investigations, and Transportation Security Administration, among others.
Since the creation of the LECC in 1981, it has sponsored or conducted numerous training seminars, with thousands of participants. All federal law enforcement agencies, the Idaho State Police, Idaho Bureau of Homeland Security, county prosecuting attorneys, county sheriffs, police chiefs, detectives, patrol officers, tribal law enforcement, university police and security officers, corporate and private security services, community organizations, elected officials and school administrators have been made aware of the role and responsibilities of the U.S. Attorney's Office and have worked with the office. One of the highlights of the LECC's history was the first-ever street gang training, which was offered even before Idaho began to see evidence of gang activity.
