Robert DeArment's BAT MASTERSON was one of the first biographies of a Old West character that was rigorously researched. using as many primary sources as available at the time, and with sources footnoted. Without books like DeArment's showing others the way to produce Lawman/Outlaw books as serious history, we would not be where we are today. I don't disagree with anything y'all are pointing out, just that any critique of his early writing must be given in context. He corrected the great majority of his mistakes in BAT MASTERSON in his later indispensable writings, including GUNFIGHTER IN GOTHAM: BAT MASTERSON IN NEW YORK.
