To compete, even CNN would have been forced to put on the "experts" explaining how long the girl struggled to breathe in that air pocket, and how her terror increased her oxygen intake.

Ted Kennedy is one of the most despicable political figures in American history.
At least Vince Foster was put down with a single shot to the head.
