tarflyonthewall, I disagree with you as well.
TAR films in public places. In this era with continuous internet connections (or mobile connections) twitter, phonecams, and what have you, the show isn't going to be able to prevent anyone from reporting what they see, or conversations that they may have (unless the producers get the confidentiality/filming waivers signed.) At this point, the show is fully aware of what may happen, and that they'll face this in some areas of the world more than others.
LAX, in particular, is something I think they've decided to live with. Even the employees there are well aware of when TAR is filming on the premises. While some legs have been well spoiled the last two cycles, others have remained totally obscured, or nearly so.
What I do agree with is that observers of the filming should not directly interfere with the filming. Observe and report to their heart's content, but observe and do not interfere. It's pretty clear to me the show has figured out to use places that are not totally open for tasks (such as the Speed Bump and U-Turn) and this season's use of local "containers" for clue holders is a very clever way of hiding the clues in plain sight.
