(Undated) -- Amanda Knox says condemnation doesn't stop for people who are cleared after being wrongfully convicted of serious crimes. The Seattle woman was convicted, then cleared twice by Italian courts of the 2007 murder of her British roommate Meredith Kercher. Knox writes, in a long op-ed in today's "USA Today," that she's still the target of an endless stream of social media insults and threats. Knox says she did not get her old life back when she returned home last year after being fully acquitted by Italy's highest court. She writes that no one who is exonerated ever gets their old life back.
