If everyone driving down a highway is going above the speed limit, are they all doing the wrong thing? Do they all risk being singled out by the highway patrol?

If everyone driving down a highway is going above the speed limit, are they all doing the wrong thing? Do they all risk being singled out by the highway patrol? If everyone wears a mask, or at least the majority, can those being singled out for wearing one use some sort of argument that everyone was wearing one? At what point does a "lawful protest" become an "illegal riot" because if the former turns into the latter all of a sudden, can you argue your way out of it? In any event, seems as ridiculous as charging illegal downloaders hundreds of thousands, rather than something reasonable, for downloading an album, or what-have-you.
