There was a good article in a magazine a few years ago, by a member of the 6th Cavalry who was stationed just outside Tombstone. He actually knew all the characters and didn’t think much of them.
He said Wyatt Earp was a pimp who pinned on the badge only when it was to his advantage. He thought Doc Holliday was an insane killer.
I read several similar stories in Western magazines 44 years ago. One even said the Earp clan often robbed stage coaches in the area.
Must have been an old article, since the late 1800s was when those men lived.
Doc Holliday was a very educated man, with a gentle attitude and manners, he came from a middle class family in GA. Ironically his mother had died from tuberculosis when he was young, the he went to PA to become a dentist. Doc went to Texas...died in Colorado. Insane, no. Killer, yes, but in self defense mostly. Great marxmen are always challenged by idiots.
