"Here is the easiest way to explain the genius of Johnny Cash: Singing from the perspective of a convicted murderer in the song 'Folsom Prison Blues', Cash is struck by pangs of regret when he sits in his cell and hears a distant train whistle. This is because people on that train are 'probably drinkin' coffee'. And this is also why Cash seems completely credible as a felon: He doesn't want freedom or friendship or Jesus or a new lawyer. He wants coffee.

Within the mind of a killer, complex feelings are eerily simple.

This is why killers can shoot men in Reno just to watch them die, and the rest of us usually can't."
