Erik my friend, it is a history error to automatically assume that all false claims were made by Wyatt Earp.
One example: Stuart Lake's Frontier Mashall. Lake did not send a one-time manuscript to his publishers.
This MS was returned to Lake several times with suggestions and corrections including the request for re-writes.
The publishers informed Lake several times that a Book should be "based" upon a story, not the story itself.

On the other end of the push-pull spectrum, Josie was also demanding changes and deletions of the manuscript. She even threatened litigation.

Lake could have saved a lot of money per his expensive and travel research.
