Sheriff's deputy Darrell Mathis of Newton County, Ga. (30 miles east of Atlanta), a five-year veteran, was arrested in September and charged with selling marijuana locally — from his squad car, in uniform, and apparently without inhibition. A confidential informant, unnerved by Mathis' alleged brazenness, convinced FBI agents in April 2013 to do a by-the-book sting (with which Mathis, of course, naïvely cooperated, according to bureau affidavits). In their final meeting before the arrest, for example, Mathis took pains to assure agents: "Don't worry. I'm on your side." He was reportedly enthusiastic about the sting's plan to run marijuana and cocaine from Alabama to North Carolina.
