‘Secrets of Interrogation’ is a fascinating programme that uncovers the powerful techniques detectives use to persuade guilty offenders to confess. When tried and tested means such as DNA tests and circumstantial evidence fail, confronting a suspect face-to-face might be the only chance police have to reveal the truth about a crime. In this series, watch as dramatic re-enactments demonstrate how the experts see through deception. Learn whether it is possible for the innocent to prevail when they are facing a professional interrogator and how the power of psychology helps to lift the secrecy on acts of malice and revenge.
