Can expert witnesses change criminal justice systems? Author and criminal psychologist Dr Julia Shaw lays bare the secret world of expert witnesses. An expert on the reliability of memory, she has submitted evidence in more than 50 trials in the UK, US, and Canada. In this series, she dives into five seminal legal cases where the outcome hinged on a crucial piece of expert evidence.

In this episode, Julia tells the story of the Guildford Four, -four young people who confessed to the IRA bombing of a pub in Guildford in 1974. Professor Gisli Gudjonsson, a forensic psychologist, provided expert evidence in the appeal showing how the wrong interrogation tactics can lead to miscarriages of justice.

Dr Julia Shaw speaks with professor Lawrence Allison, an investigative and forensic psychologist. They speak about the correct way to interview terrorism suspects, false confessions, and the ways in which expert evidence can change criminal justice systems for the better.
