On January 8, 2011, twenty-two-year-old Jared Lee Loughner opened fire at a Tucson meet and greet held by US representative Gabrielle Giffords. The incident left six people dead and thirteen injured, including Giffords, whom he shot in the head. Tom Zoellner, a longtime friend of Giffords’ and member of her congressional campaign, uses the tragedy as a jumping-off point to expose the fault lines in Arizona’s political and socioeconomic landscape that allowed this to happen: the harmful political rhetoric, the inept state government, the lingering effects of the housing market’s boom and bust, the proliferation of guns, and the hysteria surrounding issues of race and immigration. Zoellner offers a revealing portrait of the southwestern state at a critical moment in history—and as a symbol of the nation’s discontents and uncertainties.
