Yeah... but they could also not wear a badge. I doubt that'll fly

Any reasonable court would find that wearing a badge in a manner that obscured the number or name would not be "clearly wearing" said badge. Is the officer an ethical person who makes a good faith attempt to follow the law they're hired to uphold, and will the court be reasonable are both questions that don't change what the law clearly expects and requires.
