Post-9/11 Mass Surveillance

Coverage from Schneier on Security, Pagosa Daily Post, and others

Post-9/11 Mass Surveillance topic image

After the September 11 attacks, U.

S. surveillance grew beyond targeted counterterrorism investigations through expanded legal authorities and information-sharing among federal, state, and local agencies. Police and intelligence agencies draw on location records, biometric and camera systems, data brokers, and automated analysis to connect information across sources. The same framework raises lasting questions about oversight, effectiveness, privacy, and the risk that surveillance can be misused or chill speech and organizing, particularly for communities subject to heightened scrutiny.
