The choice is to run now or fight extradition later. She can't do both since she will be arrested when the extradition is requested.
If I were her, I would have been there already!
Was thinking about extradition and double jeopardy. Since the double jeopardy is specifically written in to the treaty (iirc, and I think I do), I think it's an arguable basis for denying extradition. Here, if a person is found guilty and the guilty verdict is overturned entirely on appeal, you don't send them back for another trial so I think there may be a colorable argument that the Italian procedure amounts to double jeopardy. I wonder if there's any precedent for this specific scenario involving an American after the treaty was in effect. I imagine in most cases the guilty verdict would have been affirmed on appeal.
I've been wondering how this would play out if this happened, so I guess now I'll know!
