If only TV hosts had the guts to do this more often…

The longtime NBC sports and talk show host [Costas], who signed on this year to be an occasional substitute for Larry King on CNN, resisted a request last Thursday to be the host of a King program devoted to interviewing guests about the already widely covered Natalee Holloway missing-person case in Aruba.

When he could not get the show’s topic changed, Mr. Costas said he respectfully decided not to participate.
