None of the folks who complained to the FCC were actually watching the show! But oh, they could sense that it was just filthy. Filthy, naughty, dirty, reprehensible.
See for yourself, and watch the clip here. But don't expect any nudity, you pervert, this is CBS not HBO.
CBS says that 100% of the 4,211 complaints filed with the feds about this episode of "Without A Trace" came from web-based e-mail form letters originating from 2 right-wing christian groups (the PTC and the American Family Association). Only two complainers claimed to have seen the show, but made an inaccurate reference to another scene, thus blowing their cover.
But the brunt of the issue lies with a technicality in the indecency complaint process: the FCC can only consider complaints from viewers in the station's broadcast area. Therefore, CBS alleges, the PTC and AFA-initiated complaints against "Without A Trace" are invalid.
Hooray for the Freedom of Information Act!
