Unfortunately the whole “isn’t a citizen” thing might work against him. IIRC courts have ruled the Bill of Rights applies to citizens, including freedom of the press.
The whole situation is absurd though.
Oh yeah, US courts justifying their continuous rights abuses of foreign detainees is absurd and should be legitimized by no international judgements.
One more reason to not extradite Assange. Let him sit trial for everything else he’s allegedly done in countries with humane criminal justice systems, but do not subject him to either Manning’s, or worse, as you say, non-citizen’s torture in places like Guantanamo Bay.
