Second, here's the slimy little turd's 'protection'*:
Apparently Wikileaks is feeling the pressure because last week they posted an encrypted 1.4GB file on the site labeled simply as 'insurance'. It's believed to be the remainder of all classified US military documents they have and expected that Wikileaks allies would release the key should Assange be detained.
The only proper answer to this is grab his ass, charge him, and help anyone who takes harm because of his actions sue his ass off. Over and over and over. Screw playing games with this piece of crap.
