I did some reading about this case when the trial (s) were going on and I remember the evidence being flimsy to non existent, the Italian prosecuter even claimed Knox was some kind of Satan worshiper. There was ample evidence against Guede though, he even took a dump in Kerchers toilet. I don't hesitate to believe the Italians wouldn't love to just stick it to the arrogant and bullying yank as our friend Furio would say!
