a separate, autonomous agency in practice. Following the repeal of Prohibition in December 1933, the Alcohol Beverage Unit was removed from the FBI and the Justice Department, and returned to Treasury, where, coming full circle, it became the Alcohol Tax Unit of the IRS, ultimately evolving into the Bureau of Alcohol, Tobacco, and Firearms, or ATF. The present-day ATF deals mostly against illegal firearms, explosives and conducts arson investigations. In the wake of the September 11, 2001 terrorist attacks, President George W. Bush signed into law the Homeland Security Act of 2002. In addition to the creation of the Department of Homeland Security, the law shifted the ATF from the Department of the Treasury to the Department of Justice. The agency's name was changed to the Bureau of Alcohol, Tobacco, Firearms, and Explosives, or BATFE; however, it continues to be referred to as the ATF. The task of collecting federal tax revenue derived from the production of tobacco and alcohol products and the regulatory function related to protecting the public in issues related to the production of alcohol, previously handled by the ATF and the IRS, was transferred to the newly established Alcohol and Tobacco Tax and Trade Bureau (TTB), which remained within the Treasury Department. These changes took effect January 24, 2003. In popular culture Eliot Ness’s memoir, The Untouchables, went on to become a bestseller and was later adapted into two television series (in 1959 and 1993) and a feature film. Izzy and Moe, a TV-movie starring Jackie Gleason and Art Carney, was loosely based on the real life Isador Einstein and Moe Smith. The Bureau of Prohibition is featured prominently in the HBO period crime series Boardwalk Empire, particularly through the character of Agent Nelson Van Alden.
