The Untouchables - Season 1 Episode 16 The St. Louis Story

Spring 1931. Gangland warfare had broken out again with sudden violence in the streets of St. Louis. Tim Harrington, who was long entrenched as the undisputed boss of the city, was fighting off the challenge to his leadership from Joe Courtney, an upstart hoodlum. The elder Dink Conway calls for a sit-down between the two, at the Jockey Club. Dink points out they are operating the old way: shootouts and dealing in cash. He offers them organization and protection, and says the new way is to use fronts to cover your criminal activities and keep books so the Feds can't get you on income tax evasion (he knows what happened to Al Capone).
