The document discusses the history of mobsters in the 1920s. Mobsters engaged in illegal activities like bootlegging alcohol during Prohibition and being paid killers. One of the most famous was Al Capone, who rose to prominence through bank robberies, auto theft, and selling illegal booze. Mobsters like Baby Face Nelson and Al Capone became wealthy but gained notoriety through their ruthless criminal behavior and later faced imprisonment, as law enforcement increasingly cracked down on organized crime. In their heyday, some mobsters were even seen as folk heroes by some for targeting banks and destroying mortgage records during the Great Depression.
