I used to have an old WESTERNER magazine that claimed the Earps spent their “off” duty time robbing stages in AZ.
There was a 1972 series called “David L. Wolper Presents” which depicted the gunfight as though news cameras were present, in black & white with no sound except voiceover (”struck in the calf by a McLaury bullet, Virgil Earp goes down but quickly rises”). Very realistic effect.
