Daron Hall is the antithesis of the stereotypical Southern sheriff: he doesn’t like guns and it’s nearly impossible to find a photograph of him in uniform. He prefers to present his six-foot-four frame—he was a kicker on his college football team—in well-tailored suits. With his open, often smiling face, white goatee, receding hairline, and glasses, Hall looks more like a politician than a sheriff. Now sixty-one, he has been in the position longer than anyone else in Davidson County history, and he inspires fierce loyalty in his staff, many of whom have been with him since his first election. They trust Hall for the same reason that Friedmann’s admirers trusted Friedmann—Hall is devoted to his work and very good at it. Back when his reëlection was not guaranteed, he campaigned on the slogan “It’s what I do.” Like Friedmann, Hall can be self-important: the website of the sheriff’s office lists every predecessor of his since 1783. The vanity is tempered by compassion. Even Nashville conservatives don’t mind that Hall is a reform-minded Democrat who opposes the death penalty. (“I don’t think it’s the right thing until they execute rich people,” he told me.)
