This book is titled Cyber Crime and Digital Evidence for one fundamental reason: it is more likely that a lawyer or judge will encounter digital evidence in almost every case, given its ubiquity in modern life. Nearly half of this 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 criminal law that have been modified to address new forms of bad behavior that are facilitated by digital devices and networks.
