On the evening of July 7, 2016, protesters gathered in cities across the nation after police shot two black men, Philando Castile and Alton Sterling. As officers patrolled a march in Dallas, a young man stepped out of an SUV wearing a bulletproof vest and carrying a high-powered rifle. He killed five officers and wounded eleven others. It fell to a small group of cops to corner the shooter inside a community college, where a fierce gun battle was followed by a stalemate. Crisis negotiator Larry Gordon, a 21-year department veteran, spent hours bonding with the gunman - over childhood ghosts and death and racial injustice in America - while his colleagues devised an unprecedented plan to bring the night to its dramatic end.

Thompson’s minute-by-minute account includes intimate portrayals of the negotiator, a surgeon who operated on the fallen officers, a mother of four shot down in the street, and the SWAT officers tasked with stopping the gunman. Their stories go to the heart of the deeply pressing issue of race and policing in our country, and reflect America’s divide over how to view the men and woman assigned to protect us.
