Only she and her Italian boyfriend know if she's guilty or not. The legal system really failed in giving her a fair trial. The murder happened in a small town and the local authorities made a lot of mistakes, tabloids were inciting public sentiment against Amanda Knox as an evil outsider in their midst, the jury was not sequestered. No legal system anywhere works 100% of the time, but her trial was not up to modern standards. I am glad she was acquitted.
