OBVIOUSLY, since the DNC insiders can verify the legitimacy of the hacked emails, and Wasserman resigned, it makes sense that at least some of her emails were not altered.
How do you know that all the emails were not altered?
How do I know that the flying spaghetti monster didn't create the universe from a meatball?
In both cases the answer is that there is utterly no evidence to support the rather absurd conclusion.
You still cannot answer the question about who hacked those emails and what their motivation was.
You are not an objective analyst.
WikiLeaks hacked the emails and their motivation is to expose the corruption of our government.
