Some of the law officers who served the West during the last half of the nineteenth century drifted from one side of the law to the other and sold their talents to whichever side offered the most advantage. Others used their positions as cover for their criminal activities. The lawmen in this book were serious offenders against the laws they had at one time sworn to uphold. Their skills were honed in range wars and family feuds and polished along the cattle trails, in the saloons and banks, and on the trains of the West. Some of them did good work enforcing the law when that was their job. Others had equally successful careers on the other side of the law. More than one kicked out their lives at the end of ropes strung up by citizens who were outraged by their abuse of the trust that went along with the badge they wore. These are their stories.
