Sorry, but I don't know more.
I was expecting the court to confirm the guilty verdicts. My thinking was, ok, this very court overturned the acquittal and sent the case back with instructions to convict. Now they have gotten what they asked for, so they will probably accept it.
At the same time, I was not surprised when they rendered the verdict they did. Accepting Nencini's decision, and his execrable report, would not exactly resolve matters, eh? Then they would have had to arrest Raffaele and cart him off to prison, even though nobody cares about him, whereas Amanda, the target of their obsession, would remain free. They would have had to subject their whole rotten process to a peer review by a US court if they even tried to get her back. That would have sucked for them, and they would have lost.
It really made sense to for them to face reality and put a stop to the bleeding. It was truth, justice and self-interest in the stroke of a pen - at the cost of pissing off lots of people inside their system.
So, I honestly did not know what to expect on Friday. Amanda and her family didn't know, either. They don't know the bureaucratic thinking behind the verdict any more than we do. What we all know is that she and Raffaele are completely innocent, so the verdict was correct.
