I'm not one for conspiracy theories, but this is all a little dodgy.
Obviously I can't comment on whether there's any substance to the charges, but Counterpunch suggests otherwise
Swedish bloggers uncovered the full story in a few hours. The complaint was lodged by a radical feminist Anna Ardin, 30, a one-time intern in the Swedish Foreign Service. She's spokeswoman for Broderskapsrörelsen, the liberation theology-like Christian organization affiliated with Sweden's Social Democratic Party. She had invited Julian Assange to a crayfish party, and they had enjoyed some quality time together. When Ardin discovered that Julian shared a similar experience with a 20-year-old woman a day or two later, she obtained the younger woman's cooperation in declaring before the police that changing partners in so rapid a manner constituted a sort of deceit. And deceit is a sort of rape. The prosecutor immediately issued an arrest warrant, and the press was duly notified. Once the facts were examined in the cold light of day, the charge of rape seemed ludicrous and was immediately dropped. In the meantime the younger woman, perhaps realizing how she had been used, withdrew her report, leaving the vengeful Anna Ardin standing alone.
Ardin has written and published on her blog a "revenge instruction", describing how to commit a complete character assassination to legally destroy a person who "should be punished for what he did". If the offence was of a sexual nature, the revenge also must also be sex-related, she wrote.
I think that the timing of the allegations (which first surfaced after the previous wikileaks disclosures) and the INTERPOL warrant is suggestive of a politically-motivated disinformation campaign rather than an actual serious criminal investigation. I also note with interest the way the charges were originally brought, then withdrawn, then brought again. Rape is an extremely serious charge, and generally treated as such in Sweden. So what's up with this?
Your guess is as good as mine, but my guess is this: Assange is stomping on the bunions of the rich and powerful. And while serious people aren't suggesting murder or prosecution for treason — either of which would make a martyr of him and underscore the seriousness of his project; I'll note that only un-serious politicians, whoring for newspaper column-inches, are coming out with this crap — I think his enemies are fighting back with that time-honoured tactic of the scoundrel, the carefully-aimed character assassination.
Which, if you think about it, suggests he's onto something important.
