“If you want to do a good job, you can’t have too many cases on your plate,” a retired Texas Ranger told the Observer.

A man vanished from his own office, turned up dead three years later, and the case against his nephew fell apart in court. The Texas Ranger running it had barely worked a homicide. The mystique says the Rangers always get their man. The math says they average one murder case every two years and learn on the job. A family got no justice because the legend is better funded than the competence.
