And furthermore,
(from Internet analysis of the doctoring charge by Dems)
"So why doesn’t the Clinton campaign provide some evidence that emails have been doctored, like publishing original emails? Experts pointed to political calculation. By saying the emails may be inaccurate generally, the campaign can plausibly deny certain facts that the emails reveal. If they offer proof that a particular leaked email is fake, however, that risks giving the impression that any emails they do not refute are accurate. Or they just might not want the original email to become public for any number of reasons. "It boxes the campaign into a bad spot," _______ said."
