The Italian mafia is one of the most famous crime families in America. Al Capone was a mob boss for this mafia and he ordered many violent acts. He was supposedly the one who organized the valentines day massacre in which seven rival gang members were gunned down. Every one knew Capone was the one who ordered the crime but there was no evidence against him. He was eventually caught for income tax evasion. He was given a sentence of six years, was released, and died in 1947. After him there have been many more mob bosses for the Italian mafia. They still organize many different crimes and are still up and running but haven't had any activity lately.
