Jury instructions, character and ambiguity...
It sounds like a lot of the discussion here is based on differing ideas about what Knox may have said or done or should have said or done, or ambiguous circumstantial evidence. This may a useful guide: These are the model instructions that U.S. federal judges use to draft their own instructions to juries (every court and circuit is slightly different; this one is searchable).
Of particular note (my emphasis):
Section 2.18
"[Defendant] presented evidence to show that [he/she] enjoys a reputation for honesty, truthfulness and integrity in [his/her] community. Such evidence may indicate to you that it is improbable that a person of such character would commit the crime charged, and, therefore, cause you to have a reasonable doubt as to [his/her] guilt. You should consider any evidence of [defendant]’s good character along with all the other evidence in the case and give it such weight as you believe it deserves. If, when considered with all the other evidence presented during this trial, the evidence of [defendant]’s good character creates a reasonable doubt in your mind as to [his/her] guilt, you should find [him/her] not guilty."
Section 3.02 (note 4)
"...Of course, a defendant is never to be convicted on suspicion or conjecture. If, for example, you view the evidence in the case as reasonably permitting either of two conclusions—one that a defendant is guilty as charged, the other that the defendant is not guilty— you will find the defendant not guilty.
It is not sufficient for the Government to establish a probability, though a strong one, that a fact charged is more likely to be true than not true. That is not enough to meet the burden of proof beyond reasonable doubt. On the other hand, there are very few things in this world that we know with absolute certainty, and in criminal cases the law does not require proof that overcomes every possible doubt..."

I wonder whether Italian juries get similar instructions?
