Ronnie Greene is an investigative journalist for the Associated Press who teaches graduate writing at Johns Hopkins University. Before joining AP, he edited a 2014 Pulitzer Prize–winning investigation for the Center for Public Integrity. Greene spent much of his career at the Miami Herald, and he is author of Night Fire: Big Oil, Poison Air, and Margie Richard’s Fight to Save Her Town. In Shots on the Bridge: Police Violence and Cover-Up in the Wake of Katrina (Beacon Press), Greene explores one of the most dramatic cases of police violence seen in our country in the last decade—the massacre of innocent people, carried out by members of the NOPD, in the brutal, disorderly days following Hurricane Katrina. It reveals the fear that gripped the police of a city slid into anarchy, the circumstances that drove desperate survivors to the bridge, and the horror that erupted when the police opened fire.
