Actually, I don't think they will shoot Assange immediately. I think he will disappear into a black hole of some sort, unless they can use him for a show trial a la Stalin. Doesn't even matter anymore what he did. What matters is putting the fear of gawd into anyone else who is thinking of doing something that causes similar embarrassment to sufficiently rich and powerful people.
As regards the comments here, I'm not at all surprised to see the attacks on Assange. I just wonder why are they such big fans of corporate secrecy and government secrecy? (Same thing now, given our corporatist overlords.)
Occam's Razor says they are shills, probably professional abusers of your privacy, and mine.
Secrecy and anonymity are funny things, but it's a tough philosophic topic. On principle, I think that secrecy is wrong, because the truth is eventually going to come out, but it turns out to be quite easy to justify anonymity in terms of prior secret crimes and the anonymity of the perpetrators... No reason to protect the whistle-blowers if the crimes were already known to the public, eh?
However, the criminals are not worrying about eventually. They just want to die with the most toys. Their planning horizons are limited to statutes of limitations or death. Preferably the whistle-blower's death.
Any trace of privacy will soon be the ultimate luxury good. The rest of us peasants will be naked on the podium, with all our weaknesses and mistakes well known and used as sticks to threaten and control us. However, that's only the half of it. Our interests, tastes, and even our strengths will be used to manipulate and control us, too.
Returning to Assange, I actually think it was his taste in women that was used to set him up. I would say he's losing his freedom for being a sucker, but he actually lost his freedom years ago.
