At least in activist circles, this kind of situation has been around for years, and security culture evolves to deal with it. Of course, that's a bit more serious then a show, but it's the same basic problem.
In NYC becoming an undercover activist for the purpose of spying on lawful activities is illegal, as it should be, because of the Handshu agreement: http://en.wikipedia.org/wiki/Handschu_agreement
LOL - people hated this comment, but I thought it was funny that Steve (a personal friend) came back to HN to talk about police abuse (a hot topic for him).
