Well, that is probably the canary in the coal mine for a whole range of tribal issues. A more detailed report might want to look into the history of that particular topic.
Plus, the number of different ways tribes are policed from Local to BIA to State to FBI is rather daunting. The only thing more complicated is who has fish & wildlife jurisdiction.
I notice they carefully chose that picture though. I have friends and relatives on both sides of the pipeline issue and quite a lot of it is much more complicated than the narrative given in the press. It also skips quite a bit of outside money showing up, ignores they already crossed the river upstream of Williston's water treatment plant which control quite a bit of NE area, and doesn't look at why the rerouting happened. I would imagine the losses at the casino are going to be felt this winter when all the outside folks go home. I'm sure they will all feel an amazing sense of accomplishment though.
