Good question
The original question was the original question. But, even if you thought it had been properly edited, the answer is crap. Why "Bravo PBS" for a lousy, supercilious answer?
And, why do you suppose the phrasing of the sharp-edged original question would cause Miss Ifill to answer untruthfully?
Is it because Miss Ifill might feel the question accusative? Because Miss Ifill responded to the edited question defensively. As well she might, considering that the weekly show she stewards, Washington Week in Review, is gossipy and inane, and destructive to the country's welfare. There's rarely the slightest acknowledgement of the press corps gross misconduct over the last ten years on that program. A few weeks ago, Martha Raddatz led a subpanel discussing the Scott McClellan book: they were really concerned about what this book said about . . . McClellan's character, that he would betray his boss like that!!!
The truth is that the NewsHour and Washington Week in Review are unworthy offerings and ought to be scrapped. They are wasteful and destructive. This country needs and deserves better journalism, public and private.
