"To the generations of Americans raised since World War 2, the identities of criminals such as Charles "Pretty Boy" Floyd, Baby Face Nelson, "Ma" Barker, John Dillenger, and Clyde Barrow are no more real than are Luke Skywalker and Indiana Jones. After decades spent in the washing machine of popular culture, their stories have been bled of all reality, to an extent that few Americans today know who these people actually were, much less that they all rose to national prominence at the same time. They were real."
— Bryan Burrough (Public Enemies: America's Greatest Crime Wave and the Birth of the FBI, 1933-34)
