Oh I was talking about the video there.
Not really relevant to the whole pepper spray/dog thing
I just watched the video that was in OP, if that is what you're talking about. They're completely in the right. It's their land that was designated to them. Chevron is not the US government, and can't do anything on their land, without their permission.
Native American territories are essentially their own states. They have their own police force, their own system of government, their own infrastructure, etc. Everything a state has.
Your's and Tony's statements saying they'd best get with the times make no sense. They're with the times, they're just occupying their land legally and legitimately, keeping out the arrogant oil corporations trying to bud their way into their land illegally.
