Public Enemy Era
John Dillinger Wanted Poster
The 1920s and 1930s were a time of rising crime, driven at first by Prohibition and then after its repeal, taking on a life of its own. The 1930s was a period of famous gangsters such as John Dillinger, Baby Face Nelson, Bonnie and Clyde, Pretty Boy Floyd, Machine Gun Kelly, and Ma Barker. It also became known as the Public Enemies Era when the FBI began to keep "Public Enemies" lists of wanted criminals charged with crimes.
