Nefarious ne’er-do-wells, bent on leading a life of crime in the Arizona territory, knew their stock in trade had a few risks. It was hard to look innocent and inconspicuous while driving a herd of stolen horses or cattle. The encumbered perpetrators were also quite vulnerable to being pursued by an angry rancher and his hired hands. Whiskey running and small-time hold ups brought little return for the risk involved. Banks had lots of money, but they were located in towns where people didn’t take kindly to having their savings robbed, and posses could be formed quickly. That left stagecoaches and trains as likely victims. Both were especially vulnerable when pulling long grades or stopped at some remote station.
