Forst takes a fresh perspective on the assessment of criminal justice policy.Written by a scholar with extensive research experience on the ground, this book takes a fresh new approach to assessing criminal justice policies, based on their impact on errors of justice: both the error of failing to bring offenders to justice and the errors of imposing costs on innocent people and excessive costs on offenders. The book borrows from principles of error management in statistical inference and the simulation of quality control processes to develop a new framework to each major sector of the justice system: policing, prosecution, adjudication and the jury, sentencing and corrections.Written by a scholar with extensive research experience on the ground, this book takes a fresh new approach to assessing criminal justice policies, based on their impact on errors of justice: both the error of failing to bring offenders to justice and the errors of imposing costs on innocent people and excessive costs on offenders.
