A political offense means something like being charged with a crime for offending the "good name" of the prime minister (see, e.g., Turkey or India for examples).
Is there a difference? Might be my non-USA-citizen point of view, so please correct me if I'm wrong from a USA perspective and this is not retaliation for embarrassment, but the USA government is still the USA government. If the CIA tortured people in Iraq under Obama* , I don't expect it would cease to be done under Trump. (Also not if he says so, since of course you would say that. It's inhumane, and yet it happens.)
* There have been so many scandals, forgive me if the torture one wasn't actually in Iraq or wasn't under Obama or something. It's just meant as an example of the inhumane stuff that is revealed about the USA thanks to people like Chelsea Manning, Julian Assange, etc.
Can you cite any case law making the argument that criminal behavior removes freedom of the press protections?
But it is in Sweden. That fact is conveniently forgotten when people were and continue to push the narrative of "Assange shouldn't be extradited to Sweden because they'll hand him over to the US".
Obviously, Assange was more worried about the rape charges--he waited until the statute of limitations on filing charges expired before he agreed to talk to the investigators.
The article also slyly paints him in a negative light just for resisting what he considered to be an unlawful arrest, which is the natural right of any human being.
