IMO that should be one of those cases where if no one complains then no harm no foul, but if someone does complain, then the police are right to stop it. A lot of those bylaws are really about settling disputes so that they don’t turn violent rather than strictly prohibiting behaviours.

And cops who go around enforcing them without receiving a complaint are just power trippers or neurodivergent in a way that makes them obsess about following rules (who shouldn’t be given any real power).
