I mean, in my country, it's increasingly unclear to me whether things like "loudly criticizing the executive branch" are now considered criminal. Recent executive branch statements on this issue seem to indicate that they may consider some critics criminal just for being critics. But it's hard to be sure. And so far, every critic they've threatened to arrest has also been accused of committing other crimes.

So "the government only considers a duress PIN illegal if it is used to facilitate crime" seems like a potentially tricky standard to apply.
