When Ray and Vi Donovan left court after the sentencing of three boys who murdered their 18-year-old son, Christopher, they said they had justice for Chris, but not the truth. They still didn’t know why Christopher was murdered on a May evening in 2001. That was a question the trial didn’t answer and only Christopher’s killers could.

Years later, they would meet the three boys, by now men, to ask that question - why? Criminal justice asks what laws have been broken, who broke them, and how the lawbreaker should be punished. But Ray and Vi needed different questions answered. They started to go through a restorative justice process - an alternative way of understanding crime that centred on their needs as victims, which Ray says is ‘not rocket science, it’s two people talking’.

Ray and Vi spent months preparing for each meeting, thinking about what they needed to know and what they wanted to happen afterwards. Until they met and talked with each of these three men. In this episode of Sideways, Ray and Vi tell of how restorative justice changed them. Matthew Syed examines the philosophy underpinning restorative justice, asking what needs it seeks to address and its relationship to criminal justice.
