on a clear morning this past February, the inmates in the B Yard of Pelican Bay State Prison filed out of their cellblock a few at a time and let a cool, salty breeze blow across their bodies. Their home, the California prison system’s permanent address for its most hardened gangsters, is in Crescent City, on the edge of a redwood forest—about four miles from the Pacific Ocean in one direction and 20 miles from the Oregon border in the other. This is their yard time.
Most of the inmates belong to one of California’s six main prison gangs: Nuestra Familia, the Mexican Mafia, the Aryan Brotherhood, the Black Guerrilla Family, the Northern Structure, or the Nazi Lowriders (the last two are offshoots of Nuestra Familia and the Aryan Brotherhood, respectively). The inmates interact like volatile chemicals: if you open their cells in such a way as to put, say, a lone member of Nuestra Familia in a crowd of Mexican Mafia, the mix can explode violently. So the guards release them in a careful order.
