Do you have information as to what is "normal" after a false confession or accusation? Are there studies as to how long it takes a person to recant? I'd love to see some case studies, even -- to see what you base your knowledge of what Amanda Knox should have done if she were forced into making a statement.
If she were to recant within a couple of days, would that be enough for you? Within a few hours? I hope that you are not hold her to an impossibly high standard.
... If you know the history of the case, then you know that hours after her statements... the afternoon of the 6th (the two confession statements were signed approx. 1:30 am and 5:45 am that day) Amanda wrote what has been termed her "gift" note.
In addition, she wrote a note to the police the next day, the seventh, after her arrest. The only place I have found the text of this note is in her book, Waiting to Be Heard (chapter 13). It was, however, referenced during her testimony.
I'm not sure what you are refencing in regard to telling a family member that she lied about Patrick. Do you have a cite? I have shown you two instances where she recanted within the first day, before she had a chance to talk to a family member or legal counsel. She was in police custody at the time she wrote both of these statements.
If Knox had clearly stated, after falsely accusing an innocent man of murder, that she felt pressured to make the statement and that there was no truth to it, everything would have been fine. The fact remains that Knox did not do this and, as a result, she was convicted of criminal activity. That earned her three years in jail.
Knox told her mother that she lied about Patrick. That was overheard when her mother visited her in jail. That information is in the court transcripts. This demonstrates that Knox knew that what she did was wrong, and we know that she did nothing to clearly straighten out the truth. If I recall correctly, the family member stated during testimony that she also kept quiet about the information because she did not speak Italian.
I have read Knox's "gift" letter where she states that she stands behind what she said about Patrick.
