Is putting your license plate in the back window on a new car until you get screws illegal?

You can read Minnesota Statutes Section 169.79 on the web web (copy it into t a search engine for a link). As I read it, there appears to be room for reasonable minds to differ over what the language means in a given situation. Perhaps you could go to court and persuade them to drop it or continue it for dismissal. What is the outcome goal? If it were me, I'd be willing to pay some if they would reduce the fine.
