The law as the crime
The most dangerous man in Pecos County is the district attorney. Hack Walker murders immigrants with Sloop and Eugene when they're young, then spends decades climbing on top of the grave, and when the secret stirs he hires hitmen to kill everyone who knows it—including his old friend. He tells Reacher, 'I'm the law in Pecos County,' and means it as a threat. The book's point is that a badge and an office can be the biggest weapon in the room, and the only answer to stolen law is someone willing to say 'Not anymore.'
