"The most important lesson I learned...was that the winner of the gunplay usually was the one who took his time. The second was that, if I hoped to live on the frontier, I would shun flashy trick-shooting - grandstand play - as I would poison...In all my life as a frontier peace officer, I did not know a really proficient gunfighter who had anything but contempt for the gun-fanner, or the man who literally shot from the hip."
Hint: "frontier peace officer" should suffice for now.
