On August 2, 1876, a gunman put a bullet in the back of Wild Bill Hickok's head at a Deadwood poker table, and the miners' court that let his killer walk free was sitting on land the United States government had already promised to someone else. This episode holds the frontier legend, the lawless boomtown, and the broken treaty underneath it side by side, and follows the debt from that theft all the way to a court case still unresolved a century and a half later. It is a story about which laws get enforced, which get ignored, and who gets to decide.
