"You know honey, I heard that one of the Smurfs here - I can't remember what their name was - raped and murdered a young girl. The agency still hasn't addressed it."

As for recording, I don't like it, but the airport is too public a place to expect any privacy. I would always assume that someone might be eavesdropping. Of course, if I saw someone with a parabolic mic, I might mention it to a LEO. If I don't know who installed the hanging mics I may end up doing that about those as well. After all, if the TSA isn't claiming they belong to them.
