Police departments across the country have started treating a pair of glasses as a national security problem. Ray-Ban Meta smart glasses look like ordinary eyewear, record video and audio through a hidden camera, and have already captured footage inside jails, detention centers and, according to the FBI, the travel route of a mass-casualty attacker. A dozen internal memos, obtained through a freedom-of-information request, show just how nervous law enforcement has gotten.

NYPD’s counterterrorism unit ordered inspections of every pair of glasses
In January, the New York Police Department’s counterterrorism unit flagged Ray-Ban Meta glasses as a “security and counterintelligence” threat. The bureau, which works directly with the FBI, told officers to inspect all eyewear allowed into inmate cells. Its worry: arrested people wearing the glasses could quietly capture cell layouts, camera placements and officer patrol routines, then post the footage online for anyone to see. Two videos already had.
A TikTok video exposed the inside of a jail under federal investigation
One of those videos surfaced in July 2025, filmed inside a South Carolina detention center already facing a federal probe over unsafe conditions. The wearer captured a shower area, holding cells and a packed cafeteria, along with detainees who had no idea they were on camera. “People don’t know about Meta glasses,” he said in the clip. His blinking recording light went almost entirely unnoticed among people who’d had every other device confiscated.
Maine’s fusion center warned the glasses could be used to dox officers
The concern spread fast. Homeland Security fusion centers in New York, Maine, Virginia, Tennessee and San Diego circulated their own warnings. Maine’s June memo went further, cautioning that some smart glasses run AI software capable of facial recognition, technology that could identify off-duty officers in public and link them to personal information, a process security officials describe as doxing.
ICE told its own agents to leave the glasses at home
By August, federal agencies started restricting their own workforce. Immigration and Customs Enforcement classified Meta glasses as body-worn cameras, banning them from any “federal workspace.” Acting director David Venturella warned in a memo that the devices “could unintentionally capture, record or transmit sensitive information.” The agency built its own surveillance tools. It clearly didn’t want them turned around on its own staff.
Meta says the blinking light makes the glasses impossible to hide
Meta pushed back on the idea that its glasses are built for stealth. A company spokesperson said every pair has a bright white LED that blinks whenever a photo or video is captured, one that can’t be switched off and disables the camera entirely if it’s covered or tampered with. Critics counter that a small light is easy to miss in a dim cell or a crowded room.
A New Year’s Day attacker wore the glasses months before killing 14
Law enforcement’s fear goes beyond privacy. Investigators say the man who drove a truck into a Bourbon Street crowd on New Year’s Day 2025, killing 14 people, had biked through the French Quarter twice in the months before, recording the area with Meta glasses. The FBI called it pre-attack reconnaissance, hands-free and nearly impossible to spot from the street.
Researchers warn the same design could reach school shootings next
Security researchers at the Lowy Institute argue the glasses don’t hand extremists new capabilities so much as make old ones easier and less conspicuous. A separate analysis from David Riedman at Idaho State University goes further, warning the technology could let radicalized teenagers livestream school shootings without holding a phone or a GoPro.
Critics say police only object to surveillance when it points at them
Privacy advocates see hypocrisy in law enforcement’s alarm. Ryan Shapiro of Property of the People, the group that obtained the memos, argues police “surveil the public incessantly” yet call it a security threat the moment cameras turn back on them. Fight for the Future’s Evan Greer put it more bluntly: there’s no such thing as smart glasses that only work for “the good guys.”
The real fight over smart glasses is about who gets to watch whom
A pair of glasses has turned into a test case for how police, federal agencies and the public will handle a wave of discreet, AI-powered devices. Officers want surveillance tools for themselves while resisting the same scrutiny turned back on them. That tension, not any single memo, is the real story behind a dozen previously unreported documents on policing in the smart glasses era.
