Border Patrol is pulling (non-white) people off buses as far north as Ohio, and demanding proof of citizenship.
If you’ve ever watched The Hunt for Red October, you’ll recall that the Russian defectors discuss freedom in terms of a a lack of need for papers to travel:
Capt. Vasili Borodin: I will live in Montana. And I will marry a round American woman and raise rabbits, and she will cook them for me. And I will have a pickup truck… maybe even a “recreational vehicle.” And drive from state to state. Do they let you do that?
Captain Ramius: I suppose.
Borodin: No papers?
Ramius: No papers, state to state.
That’s all it takes to distinguish a free state from an oppressive one. “No papers.”
