FBI and extortion
So, I read in this fine article that "Having been threatened with having his child forcibly removed for adoption unless he identified his fellow hackers, single father Monsegur is said to have passed on information to the Federal Bureau of Investigation (FBI)."
The use alone of such criminal - and dare I say: inhuman - methods should be reason enough to deny the extradition request.Though, mind me, I would love to see Assange being put to trial for his often shady activities.
