During the Prohibition Era, Dragna and his brother Gaetano (now named Tom) ran extortion and illegal liquor distillation operations.As boss, Dragna's chief source of income came from extorting local bookmakers for "protection" money, although he was also the main illegal gambling operator in the city.When Benjamin "Bugsy" Siegel, an associate of the New York Luciano crime family, relocated to the West Coast during the late 1930s, he started his own rackets and formed an uneasy relationship with Dragna.Although many sources speak of a rivalry between them, Dragna and Siegel worked closely together, especially at organizing a racing wire service on the West Coast.[6] In June 1947, the East Coast crime families murdered Siegel in Beverly Hills due to his failure to properly manage the new Flamingo Hotel in Las Vegas.[8] Cohen was also questioned in the hearings, and as a result was convicted of federal tax evasion and was forced to give up control of his rackets to the Los Angeles family.However, in the 1950s, the Los Angeles Police Department (LAPD) under Chief William H. Parker engaged in a campaign of harassment against organized crime figures.When his wife Frances died in 1953, Dragna lost interest in running the Los Angeles family and instead focused on meeting new women.
