Surveillance presents a conundrum: how to ensure safety, stability, and efficiency while respecting privacy and individual liberty. From police officers to corporations to intelligence agencies, surveillance law is tasked with striking this difficult and delicate balance. That challenge is compounded by ever-changing technologies and evolving social norms. Following the revelations of Edward Snowden and a host of private-sector controversies, there is intense interest among policymakers, business leaders, attorneys, academics, students, and the public regarding legal, technological, and policy issues relating to surveillance. This Handbook documents and organizes these conversations, bringing together some of the most thoughtful and impactful contributors to contemporary surveillance debates, policies, and practices. Its pages explore surveillance techniques and technologies; their value for law enforcement, national security, and private enterprise; their impacts on citizens and communities; and the many ways societies do - and should - regulate surveillance.

'Professors Gray and Henderson have assembled a comprehensive and thought-provoking collection of essays by many of the leading thinkers on surveillance law. This handbook is a perfect first stop for any scholar or citizen interested in the field. My students and I have already begun to benefit from their work.'

Richard E. Myers - Henry Brandis Distinguished Professor of Law, University of North Carolina School of Law

'In many debates about privacy and security, I’ve emphasized it is not a battle between the forces of light and darkness. It is essentially a discussion among free people as to how to balance things that they actually want (but cannot have) in full measure. That’s why The Cambridge Handbook of Surveillance Law is so important - it adds to the reasoned debate we must have.'

Michael Hayden - Principal at the Chertoff Group and former Director of the Central Intelligence Agency

'The Cambridge Handbook of Surveillance Law is a superb contribution to the debate about surveillance. Pushing far beyond typical generalities about surveillance, this book contains essays of great depth and focus. The result is a volume with a fresh and nuanced set of perspectives addressing cutting-edge issues. The editors have assembled an all-star group of contributors. This is a truly outstanding volume, one that is essential reading.'
