Is Assange now unprosecutable?

That recent leak of America's hacking secrets comes at an opportune time for Assange.  He may have to leave that embassy in London within a few months.  Generally, and unlike MY trial, a Federal criminal defendant gets great leeway to call witnesses for his defense.  Now that he has published the 'keys to the kingdom', I doubt whether it would even be possible to prosecute him.  Imagine all the witnesses he could call just to verify the genuineness of those recent documents! No doubt the person or people who leaked that material to Wikileaks knew this.   Somebody deserves some big congratulations.                Jim Bell
