This is a story a day or two old. My recollection -- and I might be mistaken -- is that the Carroll story didn't really break out for about a week, until her captors released a hostage video on the Web. Before that, everyone hung back and let the CSM take point. The Carroll story was pointedly not front and center, because negotiations and rescue plans were brewing behind the scenes.
That is journalism, and Fox is shirking its responsibility.
Fox has a responsibility to report the news, and it has a responsibility to its people. They're balancing those responsibilities, under considerable emotional strain. I'm not inclined to second-guess. We know the essential facts: An American TV correspondent and his crew were abducted. We don't need hourly updates until he's safe and home.
