Gangsters are individuals involved in organized crime, often associated with illegal activities such as drug trafficking, extortion, and racketeering. They typically operate within a structured group known as a crime syndicate, which can vary in size and influence. Gangsters often use violence and intimidation to maintain control and protect their interests. Historically, gangsters have been prominent in various cultures, particularly during the Prohibition era in the United States, when the illegal sale of alcohol led to the rise of powerful crime families like the Chicago Outfit. These groups have been depicted in numerous films and books, contributing to the public's fascination with their lifestyles and operations.
