In January, the New York Police Department's counterterrorism unit sent out a memo warning police officers about a new potential "security and counterintelligence" threat: Ray-Ban Meta glasses. The memo directed officers to "conduct thorough inspections of all eyewear permitted within inmate cells" and cautioned that people who have been arrested could use these glasses, equipped with small cameras and microphones, to record inside police facilities. The memo cited two examples of such videos posted on social media.
