Yeah, fair comment I guess though that doesn’t necessarily say that we really know what actually happened, just that it’s very unlikely that he wasn’t involved.
EDIT – he has appealed, just didn’t get the verdict overruled. He still claims to be innocent.
My point being that a conviction only tells us what the court has decided. Unless we believe it’s infallible, all we’ve learnt from the Knox appeal is that the court doesn’t believe that the conviction was legally sound, not that she was innocent. No idea of the details of it as I haven’t really followed it much so I’d be interested to know if there’s other evidence that does make them look guilty but maybe doesn’t reach the ‘reasonable doubt’ requirement or whatever else Italian law requires.
