Amanda Knox broke down in tears as she appeared at a criminal justice festival in Italy this morning.

Knox, who fought a bitter legal battle against the Italian justice system, broke down in tears as she told the crowd: 'It is not enough to get it right eventually. We need to get it right sooner, to do more often than we do.'
