So the top court in Italy has acquitted them.
As long as justice has been fairly done I am happy. I have not been following this very closely but it was an odd matter. Amanda Knox seems to have had a strange life in recent days with the threat of extradition back to jail in Italy. As this was from the highest court in Italy I understand it is final.
