This text stresses the practical procedures, techniques, and applications of private and public investigations to provide students with a solid foundation in criminal investigation. The Seventh Edition emphasizes professionalism and integrates coverage of modern investigation tools as it presents established investigation policies, procedures, and techniques for the law enforcement officer. Recent court cases; coverage of the latest investigative techniques and technology; and new material on topics such as terrorism, stalking, and child abuse enhance the text's practical and applied approach. In addition, a new 8-page, full color crime scenes photos insert uses current, real-life cases to illustrate chapter topics, and a new interactive Crime and Evidence in Action CD-ROM comes packaged with each student edition.
