“As Arizona goes, so goes the nation, according to this searing book of reportage from Phoenix.

Joe Arpaio liked to call himself “America’s toughest sheriff.” A New England transplant to Phoenix, he ran for sheriff at an age when most of his peers were retiring, winning on a law-and-order ticket that targeted undocumented immigrants. Journalists Sterling and Joffe-Block were there for much of Arpaio’s 24-year tenure, during which he became infamous for housing inmates in tents in the summer heat and serving them “gloppy, tasteless, and sometimes moldy” food. As the authors note, Arpaio was an early ally of Donald Trump. Importantly, he also set the stage for Trump by making villains of undocumented workers and by ignoring numerous court orders to cease race-based policing. In the end, that led to a conviction for contempt of court, which might have earned Arpaio jail time but instead led to a Trump pardon. Inarguably, Arpaio’s strong-arm tactics had an effect: “One estimate found that about 92,000 unauthorized immigrants of working age—about 17 percent of that cohort—left Arizona between 2008 and 2009.” Sterling and Joffe-Block diligently chronicle the work of immigration rights activists and undocumented workers while also focusing closely on Arpaio, who, like Trump, professed to despise the press while craving its attention. They also turn in shocking stories of official malfeasance, including a case where a sheriff’s deputy victimized innocent suspects and malefactors alike, stealing a garage full of evidence, including Schedule 1 narcotics. Yet he was kept on the force because he produced “high stats,” immigrant arrests that enhanced Arpaio’s bragging rights. Finally turned out of office, Arpaio lost a primary race for U.S. Senate to a Republican candidate who herself lost because Arizona was turning blue—one reason for which, the authors hint, was a direct repudiation of Arpaio and his policies.

Though it runs a touch long, this is a work of exemplary reporting.”
