My impression that Knox knows more than she divulged to the police, but 1) highly unlikely a murderer; and 2) there is no evidence that proves her participation in murder beyond reasonable doubt (actually in her case - doubts are overwhelming). If Knox verdict were upheld, it would be indeed bad news - that anyone could be easily framed for murder, any link to the murder scene is enough...
I’ve read much on this. After reading Ann Coulter I was convinced she was guilty, but after reading this I concur with you post.

Ann C. messed up on this one big time. No way this girl should be convicted.
