I'm a little confused by that one - I don't know Tenn. state law, but that seems like a public recording where there wouldn't be an expectation of privacy. My state, PA, has pretty extreme laws regarding recording/taping and you CAN tape and post a public interaction like that. Our local LEOs used to confiscate and destroy cameras...then try charging the recorder with wiretapping/disorderly conduct but courts repeatedly found that video recording in public wasn't a violation of our wiretap statutes.
