I didn't end up taking any action afterward. Partly because I didn't know the officer's name as he never volunteered it, and I didn't have any paperwork to reference. I could've still sent an email to someone, so they could just make all their officers aware. But I really didn't want to cause problems for myself when I suppose it can be considered that I got lucky, as the officer was threatening to take me to jail and impound my car if there ever was a next time. And after that kind of speech, I can't say I'm eager to stir the pot, even if I may be in the right on the permit issue.
