A Kentucky woman was arrested on a state misdemeanor charge after she walked up to the federal “blue line” at the front entrance of the Y-12 National Security Complex on East Bear Creek Road on Saturday afternoon and sat down on the pavement at the main entrance to the nuclear weapons plant.

Ralph Hutchison, coordinator of the Oak Ridge Environmental Peace Alliance, said Rosdatter, a 55-year-old mother who has a doctorate in philosophy, did not cross the blue line. Crossing it can result in federal charges.

In an apparent act of civil disobedience, Rosdatter sat in the roadway, on the hot asphalt near the blue line. She appeared to be questioned by Y-12 security officers and the Oak Ridge Police Department and then detained by the ORPD.

Also Saturday, Michael Walli, one of three protesters who broke into Y-12 on July 28, 2012, and splashed blood and sprayed graffiti on the Highly Enriched Uranium Materials Facility as part of an effort to protest nuclear weapons, helped lead a two-mile nuclear disarmament march to Y-12 from Alvin K. Bissell Park in central Oak Ridge. Rosdatter’s arrest followed that march.

Walli was released from prison along with his two fellow protesters, Megan Rice and Greg Boertje-Obed, on May 16, 2015, eight days after the U.S. Court of Appeals for the Sixth Circuit overturned their more serious felony sabotage convictions. [Read more…]
