The loose laws you describe are a problem that needs to be solved regardless, because they allow for selective enforcement against specific people or demographics by police departments acting in bad faith. A law that everyone is technically breaking but is generally not enforced can be used to target ethnic groups, or individuals that a particular police officer has a personal vendetta against. It essentially turns the police into judges, because it gives them the guaranteed ability to get a conviction somehow against anyone they want.

I assume a way for any civilian to activate those laws against any other civilian would result in the legal code being cleaned up quite quickly.
