The split and part privatisation of the UK probation system in June 2014 saw huge changes to the service, with high risk offenders managed by the new National Probation Service and low to medium risk offenders managed by Community Rehabilitation Companies (CRCs). Two years on, probation officers report a system that has been 'ripped apart', with two sides often failing to communicate. There are concerns over rising caseloads, falling staffing levels and the number of murders committed by offenders released from prison on licence. File on 4 speaks to families who have lost loved ones, and hears how they have had to fight to find out the full extent of the failings of the probation system in their cases. Charities report particular concerns over vulnerable women in the probation system, with many being recalled to prison for breaching probation orders, following short sentences for minor offences. As Transforming Rehabilitation is scrutinised by the Public Accounts Committee and Her Majesty's Inspectorate of Probation, File on 4 asks if the changes are putting the public at risk?
