I pity anyone gullible enough to think that should Assange emerge from the Ecuadorian embassy there will be any attempt to levy genuine justice for the highly dubious charges levied against him. He would be banged up in a US supermax prison before his feet touched the ground.
I pity anyone gullible enough to believe in conspiracy theories. He has followed the UK judicial process irt the extradition proceedings to Sweden, how is that not justice? If / once extradited to Sweden he would be subject to their judicial processes, the representation, fair trial and appeals process.
It is far easier to be extradited to the US from the UK than from Sweden - see various businessmen who have been extradited to the US including the Natwest 3 over financial irregularities over Enron. I believe, not an expert in extradition though, that the level of proof required is lower in the UK and in Sweden.
