This book is more than a collection of original published articles-it is a summary of studies that have shaped the criminal justice system. Carefully chosen based on their impact on the discipline or their capacity to spark controversy, the studies offer a historical look into the field of policing, courts and corrections. Each summary includes: a complete citation; background information; a description of methodology; a summary of results; an evaluation of the research; and suggestions for further reading. Throughout the book, readers are shown a variety of research designs and evidence of research influencing the operation of the criminal justice system.
