In 1881, I really don't know if there was a Rule G, but -- if there was one -- it certainly had a different interpretation, as nearly everybody, top to bottom, on the railroad had a hollow leg, so to speak.
What could they have done for such a rule violation in remote far west Texas in 1881 -- fire the entire gang? The Commanches had only been forced to surrender two years previously, and there was nobody else out there.
