History: Prohibition Of Alcoholic Beverages, Los Angeles, California, United States

Prohibition in the United States did not apply in neighboring countries, where alcoholic drinks were not illegal. Distilleries and breweries in Canada, Mexico, and the Caribbean flourished as their products were either consumed by visiting Americans or smuggled into the United States illegally. The Detroit River, which forms part of the U.S. border with Canada, was notoriously difficult to control, especially rum-running in Windsor, Canada. When the U.S. government complained to the British that American law was being undermined by officials in Nassau, Bahamas, the head of the British Colonial Office refused to intervene. Winston Churchill believed that Prohibition was "an affront to the whole history of mankind".
During the time known as the "Roaring Twenties", Chicago became a haven for Prohibition dodgers. Many of Chicago's most notorious gangsters, including Al Capone and his enemy Bugs Moran, made millions of dollars through illegal alcohol sales. By the end of the decade Capone controlled 10,000 speakeasies in Chicago and ruled the bootlegging business from Canada to Florida. Numerous other crimes, including theft and murder, were directly linked to criminal activities in Chicago and elsewhere in violation of Prohibition.
Three federal agencies were assigned the task of enforcing the Volstead Act: the U.S. Coast Guard Office of Law Enforcement, the U.S. Treasury Department's IRS Bureau of Prohibition, and the U.S. Department of Justice Bureau of Prohibition.
