@Frank...Re: @Titus This would be an Assange view of the law.....
Typically when someone flees jurisdiction, then fights the extradition warrant, and then bugs out to a foreign embassy, you can bet someone in Sweden is going to continue to want to pursue it.
Assange wants to hide out in hopes that this dies down? That's not going to happen.
Looking at Roman Polanski, he was found guilty and jumped bail before sentencing. To this day, he can never set foot in the US. (Even though the girl he raped doesn't want to be involved and has since put the past behind her.)
One could expect the same for Sweden because Assange made this more than just a he said / she said case of rape. (non-consensual sex) He gave them the two finger'd salute. (We yanks just use one. ;-)
So he can't expect the Swedish issue to die any time soon.
To your point. If the US were to open a sealed grand jury vote to indict, because of his leaving Sweden for the UK, even if back in Sweden, The US would still require both the Swedes and the UK's permission. So that's going to be a non-starter unless of course Manning's trial reveals some nasty tid bits which is what Assange is really afraid is going to happen.
The US can wait.
You can google this, but just to be thorough...
Section 3282 of Title 18 : non-capital offense unless expressly stated shall be instituted within 5 years.
(This covers everything that isn't expressly listed separately. Its your catch all )
Section 3281 of Title 18: Capital offenses can be filed at any time. Note that while Assange may not face the death penalty, the charge still has the option of a death penalty and therefore would fall in to this bucket.
Section 3286 of Title 18: 8 year statute of limitation for non-capital terrorism charges. (But doesn't seem to be applicable depending on how you define 2332b.
Then there is Section 783(e) of Title 50 which may be applicable under the 'Subversive Activities Control Act' (whatever that means) and is good for 10 years.
So if the US has any evidence of Assange doing something other than publishing the documents, he's either going to be faced with a 10 year stay in the Embassy, or Life.
I'd say that the US has plenty of time. (IMHO if the US has evidence and can charge him under the espionage act, that's one where there is no statute of limitations and they will wait until he leaves the UK and possibly Sweden.
What I don't know is what the UK will do because of his jumping of bail. Do they get him after Sweden or do they just send him back to Australia?
