Well, at least the truckers weren't shot to death of locked up in a far away camp. I think in China, dissent is pushed more harshly. I'm not saying its heading in the right direction, but if I had to pick where to be stuck, US/Canada vs. China, I would of course not pick China.
I think they decided to make an example of one of them, the woman.
Similar to the Jan 6 protesters/trespassers who languished (are languishing?) in pre-trial detention since the event.
The line between protester and terrorist is what is most immediately convenient for the state.
In fact, I would say the Western democracies have found the solution to oppress political rebellion quite nicely. Use state controlled media to denounce protesters as terrorists, and then have at them.
