(Note, incidentally, that the DHS already has police authority within 100 miles of any border of the US; since that includes coastlines, this area includes over 60% of Americans, and eleven entire states. They also have a standing force of over 45,000 officers, and just received authorization to hire 15,000 more on Wednesday.)
…ers was meant to create chaos and pull out opposition; they never intended to hold it for too long. It wouldn’t surprise me if the goal is to create “resistance fatigue,” to get Americans to the point where they’re more likely to say “Oh, another protest? Don’t you guys ever stop?” relatively quickly.
