At about half past two in the morning on July 28, 2012, three people were dropped off at the Scarboro Church of Christ, a modest brick building with a single white spire in an African-American neighborhood of Oak Ridge. They walked through the church parking lot to a nearby dirt path, followed the path through a stand of trees, reached a meadow, and turned left. Up ahead, in the darkness, they could see the silhouette of a steep hill called Pine Ridge. On the other side of the hill was Y-12. All three had spent time in federal prison. They belonged to a loosely organized group whose members have been prosecuted by the Justice Department for violent crimes, sabotage, and threatening the national security. The three hoped to reach the uranium-storage facility before sunrise, having carefully planned the intrusion for more than a year. But they had no desire to steal anything or to make a bomb. They wanted to “heal” and “transform” the building with their own blood; to mark it as a symbol of evil, empire, and war; to protest against its role in maintaining America’s nuclear arsenal. Gregory Boertje-Obed was a Christian pacifist in his late fifties who painted houses for a living and worked with the homeless in Duluth, Minnesota. Michael Walli was a Catholic layman in his early sixties, inspired by the life of St. Francis of Assisi to live humbly and serve the poor. Megan Rice was an eighty-two-year-old nun, a member of the Society of the Holy Child Jesus. Carrying flashlights and backpacks, they headed toward the hill.
