My understanding is that gunfights never were fought the way that T.V. and Hollywood depicts them. in th dysof "The Wild West" it wasn't unusual for a man to be shot in the back while walking down the street in retribution for some insult or offense. John Wesley Hardin was shot in the back of the head by a town Deputy as a result of an insult that one of the two made about the others girlfriend. I don't remember which one did the original insulting, but the argument went on rather publicly for several dys before the Depty ended it. Wild Bill Hickcock was shot from behind by a mentaly deranged man while playing cards. The idea of the noble dual in the street at high noon just didn't happen.
