The Jimmy Savile scandal has prompted a wave of new investigations into alleged sexual abuse of children and young people, some of it dating back decades. But can the police and the criminal justice system deliver on their promise to put offenders behind bars? In The Report, Melanie Abbott investigates whether there really have been improvements in getting justice for both victims and the accused in these complex cases. What results can the public expect from the millions of pounds being spent on Operation Yewtree and the new investigation into abuse at North Wales care homes? Those who have suffered false accusations, and those who have gone through the heartache of failed attempts to prosecute their attackers reveal the human reality behind police and legal actions.
