When did videotaping TSA employees become "suspicion of interfering with a transportation facility"?

Those charges will most definitely be dropped, and they should sue the TSA as well as the local Police Department for violation of their First Amendment rights. You can only be arrested for committing a crime, not for just looking suspicious. And if there is a law that states “suspicion of interfering with a transportation facility” then it should go through the courts for its constitutionality, because that sounds like a clear violation of the Constitution.
