This past week I watched an interesting episode of Lawman entitled "Yawkey" (1960). It was written by Richard Matheson (The Twilight Zone, Star Trek, I Am Legend, The Incredible Shrinking Man, Duel, The Legend of Hell House, etc, etc...).
Spoiler Alert!
It was basically an early example of what they refer to now-a-days as "suicide by cop" where a noted gunslinger leaves the lawman with no choice except to fight him in a duel.
Everyone expects the gunslinger to win and he does indeed beat the lawman to the draw but apparently because he has tired of his life he failed to load his gun and is killed.
I couldn't figure where they were going with the plot until just before it happened as I just don't ever remember seeing this sort of storyline in shows from this period before.
