This book investigates how the Fourth Amendment can be effectively applied to digital evidence and modern policing practices. Orin Kerr, a professor of law and expert in criminal procedure, examines the friction between traditional legal protections and the realities of digital storage, encryption, and remote monitoring. He proposes a framework of equilibrium-adjustment to help courts navigate the translation of physical-world search and seizure rules into the digital domain.

Legal scholars and practitioners view this work as a significant contribution to the intersection of technology and constitutional law. Readers frequently note the clarity of the author's prose, which makes complex legal theory accessible to those without a formal background in jurisprudence.
