> I'm not a fan of rules that aren't concrete

Then you are going to have a hard time in a society filled with other humans, or living with a legal system that takes human complexity and grey areas into account in so many different ways.

Outside of a parser or a maths class, rules are rarely that concrete.

(Reading your other comments, I am sorry that your experiences have lead you to be so scared going about your day to day life that you think recording every interaction is a necessary thing to do. I'm afraid you're not going to find a lot of people who agree with that, and many who will find the idea very intrusive, though I suspect you're far from the only one in your position.

FYI if you go down this route, in some countries it is a legal, not just social, requirement that people be notified that you're recording them, particularly when it comes to audio, see one-party or two-party consent jurisdictions etc, while recording of direct threats may be legit, blanket recording of all interactions or of other people's conversations, as a precautionary measure, may not be)
