The Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) is the Federal agency primarily responsible for administering and enforcing the criminal and regulatory provisions of the Federal laws pertaining to destructive devices (bombs), explosives, and arson. Over nearly 40 years, ATF has developed scientifically proven investigative capabilities, expertise, and resources that have positioned ATF as the Nation’s primary source for explosives and fire investigative knowledge and assistance.
