Bob Costas refused to guest anchor on Larry King live because the show focused on the Aruba-missing woman story. Good for Bob. That’s a local news story that has no business on the national airwaves. Too bad there’s a bunch of journalists with no integrity happy to play the sensation card.
By the way, Costas’ late-night interview show was the best I’ve ever seen. And no, Charlie Rose doesn’t come close; he’s overrated and talks way too much.
Also, the wikipedia entry on Costas already mentions the Larry King incident. Incredible.
