I'll never believe this was accidental. Perhaps the first few seconds but after that it was too good an opportunity to make sure the President wasn't heard.
Yes, I wondered if the same guy who put the giant X over Vice President Cheney's face was in the control booth when this episode was going on.
I don't think that's it. I think they do this because they know that it will create a bigger story due to buzz than yet another Katrina speech by the President that will be forgotten the next day.
All of this Katrina coverage is "too soon," anyways.
If it was on CNN, not that many people heard it. Their ratings are, uh, er, in the toilet.....
