@pluralistic i used to watch a lot of SerpentZA—a South African Brit who had emigrated to China—and one of the things he pointed out was that basically everything was illegal, but it was rarely enforced. Only if you were “annoying” would they throw the book at you.
But if everyone is always breaking the law, they have the legal pretense to arrest anyone they want at any time—that kind of arbitrary violence is the crux of authoritarianism.
