The CIA charter demands it not operate domestically but it always has done it. The FBI, CIA, Army Intelligence infiltrate protest groups to record and communicate their actions to their handlers. As a real print journalist and Viet-Nam War veteran I assure you these agencies have people embedded among the Water Protectors. They also and always have used “provocateurs.” These people fit in and intentionally cause trouble to incite the police to retaliate, specifically used during the riots of the Sixties such as the Democratic Convention of 68 at Chicago, riots in Watts, southern Los Angeles and southern civil rights marches. MLK was surrounded by conspirators and supposedly Jesse Jackson has been an FBI informant for decades. Trust is earned and never underestimate the paranoia of the Establishment please! I can promise you they were at Ferguson, Missouri. You have to be aware of those among you. I would bet they work within Black Lives Matter for instance or Veterans for Peace. Orwell said, those who control the past control the future and those who control the present control the past. Resist!
