Video Surveillance: Information on Law Enforcement's Use of Closed-Circuit Television to Monitor Selected Federal Property in Washington, D.C.

摘要

Law enforcement use of closedcircuit television (CCTV) as a tool to fight crime and terrorism has become more prevalent over time. Civil liberties advocates have raised privacy concerns about its use. This report describes (1) the Metropolitan Police Department's and the United States Park Police's implementation of CCTV to monitor public spaces in the Washington, D.C., metropolitan area such as the National Mall and (2) the management controls they established to address privacy concerns. GAO also identified experiences of selected CCTV users that provide insights to help ensure the proper CCTV use.
