This book looks at the experience of Justice Reinvestment in the US and the challenges that this particular type of holistic, evidence-based, economically driven approach to criminal justice reform will pose in the UK. "This book provides a timely overview of the success, or otherwise, of JR (justice reinvestment) approaches as we near a new general election and the end of a political cycle? The authors are particularly strong on the application of economics in JR, emphasising the social justice aspirations of the movement as opposed to a narrower economics-based criminology informed by Rational Choice theory." - Andrew Neilson, Director of Campaigns, the Howard League for Penal Reform
