The rumors have been confirmed - tonight's show will be taped earlier in the afternoon, and the BB sites have been filled with complaints.
But I sort of get the reasoning behind it, as I don't believe it's just because of the fears of a few curses or racial epithets getting through. This is bound to be the most explosive episode in history, and tempers could lead things to get out of hand. CBS is just as afraid of hand gestures and violence as they are of the "seven words you can't say on TV". Flipping a person off can't be digitally blurred on the fly, and even the quickest control room can't guarantee that they'll make the camera changes on time.
It sucks, but is the reality of broadcast television.
