Few places in America illustrate the inequalities of the US prison-industrial complex better than California’s San Quentin State Prison.
The fortress-like facility sits by the water, surrounded by the million-dollar homes of tech executives, across the bay from the glittering wealth of San Francisco. Inside, San Quentin houses some of the state’s highest-security prisoners, and, until recently, California’s death row. It was in this prison where the fight for ending mass incarceration got an unlikely ally from the other side of the bay: Facebook founder Mark Zuckerberg.
