Since 1919, the Chicago Crime Commission has represented the Chicago business community’s efforts to reduce crime and support law enforcement. From helping to take down gangster Al Capone, creating the first Public Enemies List that was later used as the FBI's Top Ten Most Wanted, to publishing the Gang Book as a comprehensive guide to combating and understanding violent street gangs, the Chicago Crime Commission has been committed to addressing public corruption and violent crime. The Commission also maintains one of the oldest and most extensive historical archives on twentieth and twenty-first-century organized crime. Today, the CCC continues to partner with local and federal law enforcement to benefit all Chicagoans on behalf of the business community.
