"Now there is a final reason I think that Jesus says, "Love your enemies." It is this: that love has within it a redemptive power. And there is a power there that eventually transforms individuals. Just keep being friendly to that person. Just keep loving them, and they can’t stand it too long. Oh, they react in many ways in the beginning. They react with guilt feelings, and sometimes they’ll hate you a little more at that transition period, but just keep loving them. And by the power of your love they will break down under the load. That’s love, you see. It is redemptive, and this is why Jesus says love. There’s something about love that builds up and is creative. There is something about hate that tears down and is destructive. So love your enemies. (from "Loving Your Enemies")"

"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)
