This Handbook is one of a series of tools developed by UNODC to support countries in the implementation of the rule of law and the development of criminal justice reform. It is designed to be used by all actors involved in the prison system, including policymakers, legislators, prison managers, prison intelligence officers and prison staff. Members of other law enforcement bodies, non-governmental organizations and other individuals interested or active in the field of criminal justice and prison reform may find it of interest.
