Historian Steve Humphries examines failures in policies and legislation put in place to protect youngsters from sexual abuse, and discovers radical new solutions proposed by an increasing number of child-protection experts, which challenge deep-rooted attitudes and emotional reactions to paedophiles. Senior lecturer Sarah Goode believes the most promising way to reduce the number of child-abuse cases is to encourage people to seek treatment before they target victims. Her theory is supported by an interview in this programme in which Humphries meets a man who makes an extraordinary confession on camera.
