The work on Restorative Prisons led directly to a detailed examination of the concept which came to be known as Justice Reinvestment. This is a term which was coined in the United States of America to describe efforts to use funds currently being spent on imprisoning offenders more productively in those areas from which the offenders come through local community based initiatives. This approach to criminal justice gives local rather than central government the power to decide how money should be best spent to produce safer local communities.
