Native Americans versus big oil

About 2000 Native Americans from tribes all over the country have gathered in Canon Ball, North Dakota near the Standing Rock Sioux Reservation. They're waiting for a court ruling on Friday, when a federal judge will decide if construction on an oil pipeline should be stopped for an environmental impact report. Did the Army Corps of Engineers ignore Indian rights when it approved an oil pipeline under the Missouri River? The tribes claim it endangers the water supply and that sacred burial sites have already been disturbed. In the past few days, there's been violence. A new generation is raising issues that go back to America's founding — in the midst of current debate on the nation's energy supply.

NOTE: On Friday, September 9, Federal District Judge James Boasberg denied the tribes' motion for a preliminary injunction. Later that same day, Obama Administration announced that it would re-evaluate its decision on the pipeline.
