The one silver lining to this cloud of a case (biker hit by diplomat's wife in UK, who fled to America claiming diplomatic immunity) is that it might make the British judges think twice about approving the extradiiton of Julian Assange to America.
After some looking, mostly using google to find ' "Julian Assange" "extraterritoriality" ' , I haven't found anything credible justifying the extradition of Julian Assange, for any reason.
