A recent government announcement stated that anybody found to be lying about entering the UK from a red list country could face a maximum prison sentence of ten years - considerably more than some sexual offences, and even violent crime. Although serious, does the crime merit such stringent punishment? And what in any case is the purpose of punishment, when so many prisoners re-offend soon after their release? Roy Jenkins looks at some of the issues, and talks to a number of people who have all thought deeply about this, and have been guided by their Christian faith, and yet who have all come to different conclusions. Roy's guests include former solicitor and pastor Stephen Clark; restorative justice champion Julia Houlston-Clark; conservative academic Adrian Hilton of the Margaret Thatcher Centre; Chief Inspector Stuart Bell of Dyfed-Powys Police Force; and ex-offender and evangelist Peter Gladwin.
