I was having a discussion with my old man about this last night. He seems very confident that we will never see Julian Assange's face in public again.
Yeah. nah. I'd question that.
JA has become such a public face, with such a public enemy, and with such a high profile "cause" to his name, that I would be very surprised to see him "disappear."
The spooks will have to be much more subtle than that, and a character assassination (some of which has already been set in motion) is the most likely outcome.
