On trial is Jimmy Moran, who at 18 took part in a store robbery during which the storeowner's wife was shot and grievously injured. Presiding is distinguished U.S. District Judge Jed S. Rakoff, who has a longstanding interest in neuroscience and its conceivable effect on criminal law. The trial raises common questions: Is a witness lying? How reliable is eyewitness testimony? What's the best way to avoid a biased jury? How well can the defendant's intentions be judged? Alan Alda explores how brain-scanning technology is providing insights into these questions and discusses the implications of neuroscience entering the courtroom. This episode showcases the guilt phase of Moran's trial. We peer into the brains of others in the courtroom: the witnesses, judges and jurors.
