These "charges" seem to be that Assange had a one-night stand with some girl. If you were one of the millions of other guys having one-night stands that night, it's a nonissue. If you're associated with Wikileaks, you're a rapist or molestor.
Assange was charged with rape in a highly public manner. It was all over the news everywhere that Assange was a suspected rapist. The next day, it was withdrawn, because there was nothing to the case. Now they're going to do it again. Soon I'm sure he'll be a child molestor, a Satan-worshipper, a terrorist, etc. This is all politics.
And it's also nothing other than a huge distraction. Even if Assange truly were a rapist, it doesn't somehow invalidate the thousands of incriminating documents that were leaked or any of the other good work the organization does.
