Book excerpt: Cyber Crime and Digital Evidence: Materials and Cases is designed to be an accessible introduction to Cyber Crime and Digital Evidence. The title illuminates two significant aspects of this book. First, cyber crime is only a subset of a much broader trend in the criminal area, which is the use of digital evidence in virtually all criminal cases. Hence, it is important to understand the legal framework that regulates obtaining that increasingly used and important evidence. Second, this book provides a broader framework than an endless stream of cases offers. Law students deserve the broader context and, hopefully, will get some of it with this book. The second edition includes new cases, particularly United States Supreme Court cases on searching cell phones, have begun to add clarity and needed guidance to the acquisition of digital evidence procedures required of law enforcement. New technology and case law discussing the impact of that technology have been added throughout the book. This book also is available in a three-hole punched, alternative loose-leaf version printed on 8.5 x 11 inch paper with wider margins and with the same pagination as the hardbound book.
