Marshal Matt Dillon: [Walks on Boot Hill, thinking aloud] You walk around up here long enough, you start thinking there must be more dead men than there are living. Same thing a man asked me about once. "Why aren't there more Marshals than there are bad men? That way there wouldn't be so much lawbreaking!" It's a fool idea, of course, but it got me to wondering why there are any Marshals at all, it being the kind of job it is. I never could find an answer to that one. Matt Dillon, U.S. Marshal.
