Re: Not even been charged, but skipped bail.
"Also why on earth would Sweden send him to the USA?"
Because the Americans clearly want him, the whole thing with the "he didn't use a condom, so it was rape" thing is utterly ridiculous and obviously a setup. The Swedes also aren't likely to refuse a US extradition request.
Also don't discount the way the backhanded way the US judicial system works. For instance they forced an internationally routed plane to land in Europe when they thought Snowden might be on it...And there have been numerous cases where they have tricked people into flying to the US so they can arrest them. What they generally don't do is let you know in advance they want you. Assange is utterly right to be worried about the possibility.
