The Government funded a £7 million seven year research programme looking into restorative justice. In her independent evaluation, published in four reports (see links to each and an RJC summary of the entire series below) Professor Joanna Shapland found that in randomised control trials of RJ with serious offences (robbery, burglary and violent offences) by adult offenders:
The majority of victims chose to participate in face-to-face meetings with the offender, when offered by a trained facilitator
85% of victims who took part were satisfied with the process
RJ reduced the frequency of re-offending, leading to £9 savings for every £1 spent on restorative justice
Expert independent criminologists Professor Lawrence Sherman and Dr Heather Strang state that the reduction in the frequency of re-offending found in this research was 27% – that’s 27% less crime, 27% fewer victims following RJ.
Alongside the Sentencing Green Paper in December 2010 the Government published their own further analysis of the data behind the Shapland reports, quantifying the size of the reduction in the frequency of re-offending following RJ as 14%.
