This comes as more details are emerging from Thursday, including video footage of a Dakota Access security contractor holding an assault rifle, with his face covered by a bandana, apparently attempting to infiltrate a group of water protectors. A Standing Rock Sioux tribal member says he saw the man driving down Highway 1806 toward the main resistance camp with an AR-15 rifle on the passenger side of his truck. Protectors chased down his truck and then pursued him on foot in efforts to disarm him. In the video, the contractor can be seen pointing the assault rifle at the protectors as he attempts to flee into the water. He was ultimately arrested by Bureau of Indian Affairs police. Meanwhile, overnight on Saturday, water protectors reported a brush fire began near their main camp. They say they called 911, but no emergency teams responded. Protectors believe the fire was intentionally lit by people working for Dakota Access. We’ll have more on the standoff at Standing Rock later in the broadcast.
