A bill in the United States would require law enforcement to get a judges approval before conducting surveillance if enacted. The bill, called the Facial Recognition Technology Warrant Act, would require federal law enforcement to obtain a warrant from a judge to use facial recognition to track someone in real time for longer than three days, and would limit that surveillance to 30 days. It also would require the judge to report the request to U.S. court administrators for tracking. The bill, which appropriately refers to the technology rather than the delivery tool such as closed circuit TV or drones, could relieve fears about law enforcement use of drone technology in communities.
