The Jury: Murder Trial

THE JURY: MURDER TRIAL is a ground-breaking experiment that asks profound questions about how we administer justice - by putting the jury system itself on trial. For the first time ever, we examine the fairness of the system, and the inner workings of justice in the UK. Filmed over ten days, a real murder trial is recreated word-for-word from the original transcripts, and two randomly-chosen juries, neither of whom are aware of the other, are asked to judge. The case? A man who admits he killed his wife, but whose defence maintains that he lost control, and is therefore not guilty of murder. What will the two juries decide, and why? How well will they follow the complexities of the law? And after they have deliberated, will they agree with each other’s verdicts?
