Julian Assange: Wikileaks founder extradition to US blocked by UK judge

The fact that Wikileaks / Julian Assange published evidence of the US perpetrating war crimes in Irag, i.e. the shooting of civilians in Baghdad from a helicopter gunship , and their treatment of Chelsea Manning compels me to ask why the District Judge Vanessa Baraitser needed an excuse to refuse the US extradition request. 

Are no nation-states willing to uphold the international rule of law? Does the US have a get-out-of-jail card? 

Freedom of the press and the international Rule Of Law  is in everyones best interest. Having the United States acting as a rouge state is a worrying proposition.
