There are many ways we can look at it. But lets look at it from the perspective of the natives. They would see it as: "The original pipeline was meant to go under Bismark, a 90% white population. The whites complained. The company immediately rerouted it under the natives water supply. The natives protested peacefully. The company and the cops and the army attacked and started hurting people." [1]
Can we fault a population that has been historically attacked and pushed out to the fringes for perceiving the narrative that way? What more, when our cops blow off a woman's arm during a peaceful protest? [2]
