A highway patrolman once asked McDaniel to teach him how to shoot out of his car while driving, to hit a particular point on a moving car that he might be chasing. McDaniel then recalled the standardized chase scenes in the Roy Rogers and Johnny Mack Brown western movies of the 1940s and worked out a complete set of training procedures based upon the type of snap-shooting, but using the left hand, that the cowboy movie-actors routinely employed while chasing one another at a full gallop on horseback in those movies. Early the next morning McDaniel tried out those procedures on the shooting range, and later that day he taught them successfully to the patrolman.
