JOHN HARRIS BEHAN Wyatt Earp's nemesis before, during, and after the Gunfight at the OK Corral, Sheriff Johnny Behan has been generally portrayed by old West historians as corrupt and incompetent. Now, Bob Alexander, author of Dangerous Dan Tucker, sets the record straight. Through rigorous research, copious footnotes, and a lively style, Alexander reveals that Johnny Behan was an able lawman who, unlike Wyatt Earp, commonly diffused violent encounters, rather than exploiting them. Over a span of nearly 40 years, his lengthy law enforcement career was a worthy one.
