Anti-Earp writers and researchers use Frank Waters' "Earp Brothers of Tombstone", as their primary source for material that presents Wyatt Earp as something of a villainous monster, aided and abetted by his brothers who were almost brutes. Waters detested the Earps so badly that he presented a book that was terribly flawed, poorly edited, and brimming with prevarications. In his other work, Waters is poetic. In the "Earp Brothers of Tombstone", he is little more than a tabloid hack, trying to slander someone he dislikes. To date, no reason has been uncovered for the bias Frank Waters exhibited against Wyatt Earp and his brothers.
