This book is titled Cyber Crime and Digital Evidence: Materials and Cases for two fundamental reasons. First, in practicing law, it is more likely that a lawyer or judge will now encounter digital evidence in almost every case and situation, given its ubiquity in modern life. Accordingly, half of the book is devoted to the government's acquisition of digital evidence, regardless of the underlying crime. The balance of the book is devoted to various aspects of the law that have been modified to address the variety of new criminal behavior facilitated by digital devices and networks. And second, by listing "materials and cases" (in that order), the subtitle indicates that this book provides a broader framework of the cyber crime context than only an array of cases offers.
