Oddly, I have over 30 years dealing with the criminal justice system. No, I don't ascribe allegations as "proof positive"; but the fact that a grown man ran & has been in hiding for years to avoid prosecution doesn't give me confidence in his innocence. Further, he's on record lying about the emails & why he leaked them. Finally, Assange hates Clinton as he rightly considers her a threat to him:
 "We view this not as a ‘clever game’ of wiki leaks [sic] but rather as a ‘criminal act’ against the United States of America,” Abedin wrote in a previously unreleased Dec. 2, 2010, email to Clinton that laid out a way to respond to the leak. “He might think this is a clever game today, but when he is prosecuted and if convicted he will move from being a clever cyber thief to a convicted criminal and -will find out that’s a whole different kind of game.”  The "he" referred to in the email is Assange. I have no doubt he'd do pretty much anything to keep Clinton out of power. Believe Assange? No.
