Since the protesters departure, authorities have been racing to clear the site of thousands of pounds of garbage and items left behind before the campsite fills with water, and runoff from the garbage leaks into the tribes water supply, and causes major environmental damage. (My emphasis.)
And, let's remember, much of that massive pile of "garbage" is human filth discharged by those wonderful, caring "environmentalists", all of which will foul the tribe's water supply unless we Trumpster pigs pay to clean it up.
Seems like simple misdeeds are Federal crimes, if they occur on an Indian reservation.
Put out warrants for their arrest.
So when X million buffalo used to wander around there and crap they crapped antiseptic water cleaning craps?
