One of the Earp boys' favorite tactics was "bullrushing" victims from behind, sneaking up from the 6:00 and clubbing them in the back of the head. That's how they got Ike Clanton (my dad's great-uncle) the first time. Ike's crime (this time at least)? Carrying a firearm in city limits.
Actually very few gun fights, mostly shot in the back. Read the real history!
