If the cop had been pulling cars over in that area, and was still there an hour later sitting in a parking lot where he could watch traffic. YOU may have been profiled, he was sitting there looking to pull over any one that fit his twist idea of a druggie or what ever. When you said no to the search, Let you go cause he didn't have a reason to go any further. He'd have to make up some BS about why you were pulled over, can't say ""he looked like a drug dealer yer honor, and the judge say's bye, cause thats a pretty subjective reason for a traffic stop. Or your honor "I didn't like the way he looked at me from the other side of the parking lot". No law broken there. Anyhow good job on not letting a search happen.
