Window tint enforcement can change as you drive thru a city, let alone a state.
Stopped because plate was not displayed like LEO expected? In another thread that can't happen. Other issue found after that stop? Another impossibility.
Now you are talking about something more important than window tint. Does any state actually require insurance? Think they really want proof of a minimum level financial responsibility. From what you have posted, you did not show that. In my state that can lead to arrest on the spot.
