What? Yeah, well ...
"The setup plot was all about getting him in to Sweden, so they could send him to the US."
Let's assume, for just a moment, that your further comment regarding assassination and "taken out" is reasonably correct. Let us further assume that the US is trying to get him over there so they can shaft the bugger legally.
Then we got the following connundrum:
(a) The UK Court system, when all appeals are done some six months or so from now, will have to agree there is no such plot, nor any political component. They extradite him to Sweden.
(b) The Swedish Court system will have to drop the accusations. If they go ahead with charging him, he can't legally be extradited to the US before the court case is over, and - worst case for Assange - he has served his sentence.
(b.1) It's VERY likely there will be no charges. Despite three character witnesses, there's no hard proof, and if you study Swedish court records - all public domain, btw - you'll see that it is extremely difficult to get charged with, let alone condemned for, rape without MUCH harder evidence than what exist.
(c) The US would have to come up with a charge against him, complete with proof, of a crime which is ALSO a crime in Sweden - that'd get tricky, since Sweden have very good protections for publishers of material. Could be done tho; espionage would be one. But since it's reasonably clear he's NOT a spy (spies don't publish the information online, normally .... ) that's political maneouvering.
(d) The Swedish Court would have to determine whether there was a political component to the *US* request - which, uh, we all agree there would be. If there is one, they can't legally extradite.
(e) The Swedish Government would have to, according to EU law, ask the *UK* Government whether it is ok to extradite him to the US. Then the *UK* needs to say yes - and, presumably, the UK would not do so if THEY thought it had gone political-shaped.
(f) And then the US would need to make a few guarantees, such as "no death penalty", "no excessive punishment" etc before the extradition could go ahead.
So a plot to get him sent to Sweden would be tactically unsound, as the *UK* has a much softer extradition treaty with the US in the first place ....
See why I get a wee bit steamed at all this bickering all over?
But sure. They could all do it illegally. Of course, the Swedish court records would still be available to the public, so that'd get politically ... touchy.
Machiavelli would be embarrassed by this "plot".
