Is Assange alive? Is there a video of this Murray saying this recently? If he knows who did it, why won’t he tell someone? Once he is dead, who will know?
I personally think it was an inside leaker, but all these stories about what Assange may have said at some time, when no one seems to have a clue where Assange is or if he’s alive, sound pretty iffy.
Here is Craig Murray’s blog from Dec 11: https://www.craigmurray.org.uk/archives/2016/12/cias-absence-conviction/
I don’t know anything about Craig Murray, a former ambassador. He speaks as if he has some connection with Assange.
