Lawyers say the US has to use Sweden for extradition because the extradition exception laws in UK are very clear that no-one can be sent to the USA under political nature. Thus we can see how the UK was careful not to be seen as the one who handed over Assange's personal belongings to the USA. It was useful idiots Ecuador (asylum country) who gave Assange's belongings to non-custodial USA, after UK bundled J.A. out and imprisoned him on "bail jumping" charges. Nevertheless, ignoring that bail transgressions usually result in 2 - 4 week jail or a fine - not 50 weeks with solitary detention, delayed medical help, no access to internet or library, no foreign calls allowed to US lawyers or Australian family, spectacles delivered with wrong prescription causing difficulty studying legal documents, etcetera Assange's items sent to the US govt -if true - is apparently a breach in custody detainment of the UK as well as mutual assist agreements for extradition.
If we understand that the USA, all along, banks on Sweden to rendition Assange then we realise that this letter - so promptly put out just as Assange was slapped into Belmarsh - stinks:
