I already did several times, I ll do again
The US soldiers who commit crimes in Iraq and were exposed by the leaks were not punished
Totally irrelevant.
Firstly US Soldiers are not under the jurisdiction of the Swedish Courts and so Sweden has no say if they are charged or not. Assange is accused of breaking Swedish Law in Sweden, something that the Swedish Justice System can act on.
Secondly, there is no requirement for one justice system to not bring charges to bear against someone because a different justice system didn't bring worse charges against someone else.
Thirdly, those that actually can bring charges against those US Soldiers have seen the footage and stated that they did not commit a War Crime, which is why there has been no charges brought.
For the record, if civilians are killed on a battlefield because they are mistaken for insurgents, then the fault actually lies with the insurgents who aren't wearing uniforms to distinguish themselves from the surrounding civilians not the soldiers who make the mistake.
Personally I think that the helicopter crew should have watched the vehicle and directed ground troops to it for capture, but legally, the ones responsible for the killings were the insurgents, just as a bank robber is responsible for a teller's death during a robbery, even if she was shot by a cop.
Since you are not an expert in Swedish law either ( I assume), how can you tell that the quoted Australian lawyer is wrong while your right-wingish crap news site is right?
Under UK law the Swedish prosecutors cannot question Assange in the UK. They can send an application with a request for him to be questioned by police in the UK, part of which is a list of questions they would like to be asked.
If that is accepted (which it might not be) and acted on (in due course based on resources available) they might be allowed (totally at Scotland Yard's discretion) to watch the interview as a UK police officer asks the questions provided to them. They cannot intervene or ask further questions themselves. It is illegal for any person who is not a sworn UK police officer to conduct or partake in a police interview in the UK.
This is black and white in UK law, it has even been posted in this thread a number of pages back, and yet the pro-Assange still ask why the Swedish Prosecutor didn't do it. It's got to the same point of Pro-Hoaxers asking why there are no stars in the Apollo photos.
