If you are really interested in “tracking” this topic then I suggest you review search and seizure case law through the years. The US Constitution is a living document that had some amendments to it and has since been interpreted by our courts through case law. It is this case law which dictates a peace officer's ability to stop you (on foot even). Over the years the courts have further defined how strong the rights are against illegal searches and seizures in relation to vehicles. I get it that this stop (a seizure, covered under the constitution) was a minor inconvenience and if the officer was wrong it was probably just an honest mistake. If there was no violation then the stop was bad. If you’re still not tracking then I’m not the one who can help. My original statement to the OP was to congratulate him for challenging this stop. It sounds like he tried to have a civilized discussion about the stop with the officer which is the correct way to challenge a stop you believe to be illegal. Sometimes you have to go before a judge before you can prove it was a bad stop.
