This is not the first time the United States does something similar, i.e. has the authorities in country A apprehend someone who is not accused of anything there, expel him from A without notifying the country of origin, and 'somehow' have US officials waiting to arrest the 'expelled' individual on 'international' ground.
US lawyers have consistently explained that this is somehow very different from illegal extradition/kidnapping which is explicitly condemned by the UN. It only looks the same. And I very much doubt the States are the only ones doing it. The Brits and Russians have done the same.
Is it a travesty of justice? Meh, I'm not a lawyer. Is it an example of the strong getting what they want? Hell, yeah!
The only thing that makes this interesting is that the Russians will raise a more stench than usual, because the arrested individual is more than just a 'paysan'.
