If you asked me what issue Americans will see in retrospect as the greatest unacknowledged barbarity of our time, I would nominate prison rape, which is not only tolerated but frequently encouraged within our prisons and is still the subject of jokes in popular culture and politics. Ezra Klein has more here, here, and here. Warning: These posts contain graphic first-person descriptions of the attacks which go on every day within the prisons that our government controls. More than almost any other crime, prison rape is our responsibility. What will we do about it?
