@Sui @Morghur @SuperOsten @crt I understand that, and I agree with it; if I were faced with the same choice I would make the same decision.

But the choice is fundamentally wrong from the outset: You can police one person trying to get on a plane without a vax pass but you can't police all of them; an airline would balk immediately if they were facing a complete cancellation of a single flight, letalone even two.
But there was not enough courage. There never is. Too many people want to keep their heads down and not cause trouble. But it doesn't have to be trouble, just, "nah I don't care" and attempt to proceed. Then be pulled aside and let the next person do exactly the same thing.

This is why they needed the captured portion, I suppose; the zealots.
