Just to make it clear, sexual assault is a very serious matter. To say that the accusations now being made against Assange would not constitute a crime under U.S. or UK law is not to diminish the right of all women to be free from sexual assault in any form.
But these concerns have nothing to do with what is being played out in London right now. Assange has not actually been criminally charged with sexual assault, although this claim is repeated unceasingly in stories about the situation. He is wanted for questioning in a case involving such allegations; a case which was at first dismissed by a prosecutor then reopened later by a different prosecutor. This prosecutor did not charge Assange with a crime, but wanted to question him further in the process of re-examining whether formal charges are warranted.
Now here is one of the many bizarre turns in this story. Assange was in the UK after the case was re-opened. If the prosecutors wanted to question him, they could have done so at any time, either by coming to London or interviewing him via video hookup. There are ample precedents in European and Swedish law for either course. They refused to do so. (They have also refused Ecuador’s offer to have Assange interrogated in their London embassy.) Assange has also said he would return to Sweden for questioning if the government there would guarantee he would not be extradited to the United States. This was also refused.
Given the fact that Swedish prosecutors have repeatedly turned down opportunities to question Assange about the case — even though they say this is their sole aim — it is not entirely unreasonable to assume, as Assange has done, that there is some other intention behind the process that has led to the standoff we see today. If the primary concern was justice for the two women involved in the allegations, who have had the case hanging over their heads for almost two years, Assange could have been questioned by Swedish authorities at any time during that period, and the process of resolving the case, one way or another, could have moved forward. But this has not been done.
