A police officer must have reasonable suspicion that you committed an offense to pull you over. Otherwise, the stop is likely illegal, and any evidence found as a result of that stop could be suppressed. You should discuss all the details of what happened with a criminal defense lawyer to get a thorough opinion of that and any other legal issues which could help your case.
These charges are serious enough to where you need to discuss the particulars in detail with an attorney who practices criminal law in TN who can review these facts and advise you accordingly, whether you should plead guilty to a lesser charge or fight this case at trial against the prosecutor.
In the meantime, don't disucss the facts of your case with anyone until first speaking to an attorney. Good luck in court.
