It gets reported currently, with referring to an article in the WP and Wikileaks as main source, that the US have secretly sued Assange and tried to hide it in a bid to arrest him or letting him getting arrested and then handed over, if he leaves the embassay in London.
It seems his "paranoia" is fully justified from all beginning on.
The weaseling in America now, trying to explain this as a warrant that "by accident"
has a wrong name (Assange's name) on it, is an exercise in self-ridiculing.
