A collection of expert essays examines the privacy rights that have been lost in the post-9/11 era-giving students and others the knowledge they need to take back their constitutional protections.

This timely two-volume collection shares information every citizen should have, tackling the erosion of privacy rights engendered by the ability of digital technology to intercept, mine, and store personal data, most often without the knowledge of those being monitored. Examining its subject through the lens of Fourth Amendment rights, the work focuses on technological advances that now gather personal data on an unprecedented scale, whether by monitoring social media, tracking cell phones, or using thermal imaging to watch people's movement. It also examines the possible impact of the widespread gathering of such data by law enforcement and security agencies and by private corporations such as Google.

Organized by hot-button topics confronting U.S. citizens in the post-9/11 era, the work reviews the original intent of the Fourth Amendment and then traces the development and erosion of interpretations of that amendment in the 21st century. Topical essays offer a comprehensive treatment and understanding of current Fourth Amendment issues, including those that have been brought before the courts and those relative to the continuing governmental and societal emphasis on security and public safety since the Columbine shootings in 1999 and the events of September 11, 2001.
