In the late 19th century, lawlessness still plagued Oklahoma, and Tilghman helped restore order by capturing some of the most notorious bandits of the day. Over the years, Tilghman earned a well-deserved reputation for treating even the worst criminals fairly and protecting the rights of the unjustly accused. Any man in Tilghman's custody knew he was safe from angry vigilante mobs, because Tilghman had little tolerance for those who took the law into their own hands. In 1898, a wild mob lynched two young Indians who were falsely accused of raping and murdering a white woman. Tilghman arrested and secured prison terms for eight of the mob leaders and captured the real rapist-murderer. In 1924, after serving a term as an Oklahoma state legislator, making a movie about his frontier days, and serving as the police chief of Oklahoma City, Tilghman might well have been expected to quietly retire. However, the old lawman was unable to hang up his gun, and he accepted a job as city marshal in Cromwell, Oklahoma.
