Mob kingpins pulled in $100 million annually by the mid-1920s from bootlegging operations, according to federal investigators, spending $500,000 monthly on bribes to police, politicians, and agents. The term ''organized crime'' barely existed in America before Prohibition turned small-time street gangs running extortion and loansharking rackets into regional crime syndicates. Al Capone''s operation at its late-1920s peak reached $100 million in revenue from liquor distribution, speakeasies, beer brewing, gambling, prostitution, and other rackets. More than 1,000 people died in New York mob clashes during Prohibition. Chicago saw 227 gangsters killed over just four years in the late 1920s. Capone''s men dressed as police officers gunned down seven rival gang members in the 1929 St. Valentine''s Day Massacre. Homicides, burglaries, and assaults increased significantly nationwide between 1920 and 1933. Prohibition practically created organized crime in America by providing massive illegal profits that funded expansion from local thugs into sophisticated criminal enterprises.
