This is true even in things as routine daily chit-chat and conversation. Think about how often tacitly express your opinion through the way you frame a discussion and how often those environmental cues bias other parties to respond in particular ways. Then, consider how often marketers, salespeople, and other manipulators intentionally frame interactions to provoke a specific biased response.
The light touch and the small nudge are grossly undervalued.
Or the intensity of enforcement varies in the first place.
And chances are you’re doing something else illegal anyway.
Or can be followed until you do.
And if you don’t, there’s always the routine traffic stop.
someone has to decide which cases to bring, unless you fund the police and prosecutors so they can bring every plausible case, which sounds like a strictly worse universe to live in. Is this discretion abused? Yes, all the time. But bringing every case seems more like a police state than a free society.
This is (part of) the reason people spend hours debating seemingly mundane aspects of rules & regs, legislation, corporate bylaws, etc. Eventually someone will have a [dis]incentive and try to get around something.
Testing the boundaries of murder and rape laws is, of course, a different matter.
