Accountability, the idea that people, governments, and business should be held publicly accountable, is a central preoccupation of our time. Criminal justice, already a system for achieving public accountability for illegal and antisocial activities, is no exception to this preoccupation, and accountability for criminal justice therefore takes on a special significance. Seventeen original essays, most commissioned for this volume, have been collected to summarize and assess what has been happening in the area of accountability for criminal justice in English-speaking democracies with common-law traditions during the last fifteen years. Looking at the issue from a variety of disciplines, the authors' intent is to explore accountability with respect to all phases of the criminal justice system, from policing to parole.
