The battle over the future of the Dakota Access Pipeline near the Standing Rock Sioux reservation, which pits indigenous peoples and environmental activists against the forces aligned with the $3.78 billion pipeline, may reach a head this week.  Dakota and Lakota indigenous leaders have erected tipis in the path of the pipeline, and state police and local sheriff's deputies have made dozens of arrests in recent days.  Reports indicate regular targeting of reporters covering the pipeline battle.  Sandy is traveling back to Standing Rock this week.
