Police surveillance tools built around automated license plate cameras, like the ones sold by Flock Safety, are drawing fierce criticism in the United States this month, but several privacy researchers now say that’s the wrong fight. The real worry, they argue, is a quieter layer of facial recognition networks, data brokers and phone-tracking gear that operates with far less scrutiny.
Key Takeaways
- Flock Safety’s camera network, now present in thousands of American towns, is under fire for sharing license plate data with federal agencies including ICE.
- Researchers at digital rights groups say facial recognition, cell-site simulators and commercial data brokers are harder to track and arguably more invasive than license plate cameras.
- India’s own Safe City and ANPR camera rollouts raise near-identical questions, just without the same public debate happening around them.
- Experts are pushing for uniform transparency and audit rules for all police surveillance tools, rather than singling out one vendor.
What exactly is Flock, and why is it in the news?
Flock Safety is an Atlanta-based company that makes solar-powered automated license plate readers (ALPRs). Local police departments, homeowner associations and even private businesses across the US have installed its cameras at a pace that’s startled even some of its early backers.
The cameras photograph every passing vehicle, log the plate, time and location, and feed it into a searchable network that officers across different cities and states can query. Flock has marketed this as a force multiplier for small-town police forces that can’t afford round-the-clock patrols.
The backlash picked up after reporting showed that some local police departments had let federal immigration authorities search Flock’s database, despite local “sanctuary” policies limiting cooperation with ICE. That single revelation turned a useful-sounding tool into a flashpoint.
Why do experts say other police surveillance tools are scarier?
Here’s the twist in the story: several of the researchers quoted in recent coverage, including analysts at the Electronic Frontier Foundation, say Flock is actually one of the more visible and arguably accountable systems out there. At least its cameras are physical, mapped and sometimes disclosed on public registries.
Compare that to the following categories of police surveillance tools, which operate with much less public visibility.
Facial recognition networks
Live facial recognition can match a face in a crowd to a database in seconds. Unlike a license plate camera, it doesn’t just track a car, it tracks a person’s identity, in real time, often without a warrant requirement in many US jurisdictions.
Cell-site simulators
Devices often nicknamed “Stingrays” mimic mobile towers and trick nearby phones into connecting, letting police locate a device, and by extension a person, without the phone owner ever knowing. Their use is frequently covered by non-disclosure agreements that keep even defence lawyers in the dark.
Commercial data brokers
Perhaps the least regulated of all: companies that buy location data, purchase histories and app usage from ordinary commercial sources, then resell bundled profiles to law enforcement. Because the data is “purchased” rather than seized, agencies in the US have argued it sidesteps warrant requirements altogether.
Taken together, researchers say these three categories of police surveillance tools are harder for journalists, courts and ordinary citizens to even locate, let alone audit, compared with a bank of cameras bolted to a pole.
How does this compare with India’s own surveillance build-out?
This is where the story stops being a purely American argument. India has been quietly building its own version of exactly this stack for nearly a decade, through Safe City projects in Delhi, Hyderabad and several other metros, alongside Automatic Number Plate Recognition (ANPR) cameras feeding state and city traffic police networks.
Telangana’s police have run one of the more extensive facial recognition rollouts anywhere in the world, according to independent researchers who’ve tracked it. Delhi Police have used facial recognition at protests and during crowd events, a use case that mirrors the exact live-matching concern American civil liberties lawyers raise about Flock-adjacent technology.
The difference is less about the technology and more about the conversation around it. The US debate over police surveillance tools is happening in open court filings, city council votes and national newspapers. In India, procurement details, vendor contracts and audit trails for comparable systems are rarely public, and there’s no equivalent of the open camera registries some American cities maintain.
That contrast is the original insight worth sitting with: a country with famously robust First Amendment-style disclosure fights over license plate cameras is, in some ways, more transparent about its police surveillance tools than a country that talks about privacy mostly through the lens of its 2017 right-to-privacy Supreme Court judgment, but hasn’t built the same disclosure habits into state procurement.
What are officials and the companies saying?
Flock Safety has publicly pushed back on the sharpest criticism, saying it restricts how law enforcement agencies can use its network and has cut off access for departments found violating its terms, including some that shared data improperly with federal immigration authorities.
Civil liberties groups aren’t fully satisfied with that answer. They argue that self-policing by a vendor isn’t a substitute for a law, and that the same argument applies even more strongly to facial recognition vendors and data brokers, who face even fewer contractual guardrails than Flock does.
Some US lawmakers, at state and city level, have begun introducing bills requiring public disclosure of any new police surveillance tools before they’re deployed, along with annual audits. A handful of Indian privacy researchers and lawyers have floated similar proposals domestically, pointing to the Digital Personal Data Protection Act as an opening, though implementation rules specific to law enforcement surveillance remain unsettled.
A quick side-by-side of the surveillance layers in question
| Tool | What it tracks | Visibility to the public |
| ALPR networks (Flock and similar) | Vehicles, location, time | Moderate — cameras are physical and sometimes registered |
| Facial recognition | Individual identity in real time | Low — often undisclosed deployment windows |
| Cell-site simulators | Phone location and identifiers | Very low — frequently under non-disclosure agreements |
| Commercial data brokers | Location history, app and purchase data | Very low — data acquired commercially, not through warrants |
FAQ
What is Flock Safety?
Flock Safety is a US company that makes automated license plate reader cameras used by police departments, neighbourhoods and businesses to track vehicles passing through an area.
Why are people upset with Flock right now?
Reports showed some police departments let federal immigration agents search Flock’s camera network, raising concerns that local “sanctuary” protections were being bypassed.
Which police surveillance tools do experts consider more worrying than Flock?
Analysts point to live facial recognition, cell-site simulators (often called Stingrays) and commercial data brokers as harder to detect and less regulated than license plate cameras.
Does India use similar surveillance technology?
Yes. Indian cities run Safe City CCTV networks, ANPR traffic cameras and, in states like Telangana, large-scale facial recognition systems, generally with far less public disclosure than their US counterparts.
Can police legally share this data with other agencies?
In the US, this depends on local policy and vendor contracts; several disputes have centred on whether local police followed their own rules before sharing Flock data with federal agencies.
Conclusion
Flock’s cameras made an easy target because they’re visible, literally bolted to street poles. But the sharper lesson from this episode is that the police surveillance tools doing the least-watched work, facial recognition, phone trackers and data brokers, deserve at least as much scrutiny, whether that debate is happening in a US city council meeting or in an Indian state assembly that hasn’t had it yet.
