This tried and tested book provides practical guidance with specific writing samples and guidelines for producing strong reports in criminal justice-related professions. It addresses many facets of written communication in criminal justice, from police and security officer reports, to investigative findings, probation or parole reports, and other corrections forms, and forensic or scientific documentation. Criminal justice professionals often spend a large portion of their worktime writing reports. The information provided in these reports is crucial to the functioning of the justice system. Many law enforcement, security, corrections, and probation and parole officers have not had adequate training in how to provide well-written, accurate, brief, and complete reports. This book covers everything officers need to learn from basic English grammar to the difficult but often-ignored problem of creating documentation that will hold up in court. This new edition includes coverage of technological advances and potential uses of artificial intelligence in digital and electronic report writing. This book is suitable for undergraduates across the Criminal Justice curriculum as well as for police academies and other criminal justice training venues.
