This image released by NBC shows Amanda Knox during an interview on the “Today” show, Friday, Sept. 20, 2013 in New York. Knox defended her decision not to return to Italy for a new appeals trial over the 2007 killing of her British roommate, even as she acknowledged that “everything is at stake,” insisting she is innocent. In March, Italy’s supreme court ordered a new trial for Knox and her former Italian boyfriend. An appeals court in 2011 had acquitted both, overturning convictions by a lower court. Italian law cannot compel Knox to return for the new legal proceeding.
