Commonly referred to as Prohibition, it was the Volstead Act that prohibited the sale, manufacturing, transportation, and consumption of alcoholic beverages in the U.S.  N.Y.C. Mayor La Guardia summed up his belief in the failure of Prohibition this way...'It would take a police force of 250,000 to enforce the Volstead Act and another 200,000 to police the police'. La Guardia predicted that Prohibition would lead to American organized crime, bootlegging, and massive corruption through out law enforcement in this country.  He was right, the Speakeasies were everywhere.   By the mid 1920's there were over 125,000 in N.Y.C. alone.
