LOL at the responses it all depends on where you are public or private property i study practical law. From what ive learnt when youre parked in a trailer park or apartment complex cops cannot mess with you unless called if youre parked in a subdivision or on a street they can get behind you turn their lights on probable cause on suspicious character
If a cop is feeling bored and parks in a spot that he can clearly see your plate, then yes. He can search your plate or pull up to check for suspicious activity.
