NEWBERRY FOR THE DEFENSE. Stirling Newberry is a very smart guy, and this is a fascinating post. But if he's got to torture the evidence this much to get CBS off the hook, then it's more likely than not that he's wrong. And if he's right - that CBS can't present its real proof because of promises of confidentiality - then it's got a problem almost as big as it does if the documents turn out to have been forged.
