The four other points are valid defense arguments - something which were probably brought up at the UK extradition hearing and would be brought up in a Swedish trial.

However, the allegation of the charge being 'conjured up' would require that both the UK and Swedish judicial systems be severely compromised. That would be an extraordinary conspiracy, so the claim requires extraordinary evidence. The four points mentioned simply don't meet that standard in my opinion.

Extraordinary claims... A meme that has never made much sense to me. Anyway:

Think about this from the start: Assange has just become an enemy of the US due to wikileaks dumping a lot of official documents onto the Internet. Knowing this, Assange would be extra careful not to do anything that could lead to his arrest by a America-comliant government. Next thing we know, he's being accused of the one crime for which there can be almost by definition no corroborating witnesses, no forensic evidence, no signs of physical harm on the victim. What are the odds? And remember, they haven't even pressed the charges (that way they can deny the judicial system was actually compromised), this is just an excuse to get him into custody so he can then be officially extradited to the US.
