March 31, 1985. Two white patrol officers in search of a gang member followed a pickup truck carrying seven young Black men up a dirt driveway in the Encanto neighbourhood of Southeastern San Diego. Minutes later, gunshots rang out, and the truck's driver, Sagon Penn, fled the scene in an officer's patrol car. The incident stunned the city. What followed would change it forever. Penn was an idealist who believed in the power of Buddhist chants to bring about the oneness of humanity. The two police officers were rising stars in one of the most progressive police departments in the country, yet one that had suffered more officers killed in the line of duty than any other. While the facts of the case were never in dispute, what remained unresolved was what, if anything, could justify such a violent confrontation? For over two years, a determined prosecutor and a charismatic defence attorney engaged in a sensational courtroom drama that revolved around matters of mental health, racial biases, and the self-image of a once-sleepy beach town grappling with its transformation into a major metropolitan area. The Sagon Penn incident forever altered how San Diego would respond to incidents involving police and communities of colour. Based on court transcripts, personal interviews, and archival police reports, Reap the Whirlwind is a gripping true-crime narrative set against the evocative backdrop of Southern California.
