The Hollywood Reporter gossips that Les Moonves and the CBS staff were overheard "dismissing Robert Redford's Dan Rather movie Truth as 'half truth.'" Really? Sounds like snark to me.
If it wasn't sarcasm, they were being very generous. It's likely the film is a whitewash of the journalistic malfeasance perpetrated by Rather and 60 Minutes producer Mary Mapes, with the assistance of a supporting cast.
Rather got what he deserved, much like Brian Williams did. Why does pontificating every night lead anchors into the murky waters of half (or less) truths and exaggerations?
