DeFlock: How One Guy Mapped 90,000 Cameras and Sparked a Revolt

Row of surveillance cameras mounted on a wall pointing in different directions

TL;DR: An Alabama software engineer named Will Freeman got tired of watching license plate readers multiply on every street corner. So he built DeFlock, a crowdsourced map that now tracks tens of thousands of ALPR cameras across the United States. Flock Safety, the $5 billion company behind most of them, responded by sending a cease-and-desist letter. The EFF responded by representing Freeman pro bono. Then things escalated: 50+ cities canceled Flock contracts. The ACLU and EFF sued San Jose. EFF exposed 80+ police agencies using Romani stereotypes in Flock searches. People in five states started physically destroying cameras. What started as one guy’s website became the most effective grassroots surveillance resistance movement in the country.

One Map Changed Everything

Will Freeman noticed the cameras first in his hometown of Huntsville, Alabama. Small, solar-powered devices mounted on poles and signs. They didn’t look like much. But each one was an automated license plate reader: a camera that photographs every vehicle that passes, logs the plate number, timestamp, and GPS coordinates, then uploads all of it to a searchable police database ^[1].

In Huntsville, the cameras were everywhere. On residential streets. Near schools. Outside mosques and immigration centers. He started documenting their locations. Then he built a website.

DeFlock launched as a crowdsourced mapping project. Report a camera, pin it on the map. Simple. But the scale of what people found wasn’t simple at all.

As of June 2026, DeFlock has mapped tens of thousands of ALPR cameras across the United States ^[2]. Not just Flock Safety devices; Motorola and other vendors too. But Flock dominates the market, with cameras deployed in over 5,000 communities. Their network scans billions of plates per year and shares data across jurisdictions without warrants, without oversight, and without the knowledge of the people being tracked.

Freeman’s map made the invisible visible. And Flock Safety hated it.

Flock’s CEO Called Him a Terrorist

In late 2024, Flock Safety sent Freeman a cease-and-desist letter claiming trademark infringement ^[3]. The argument was thin: Freeman used the word “Flock” in his domain name to criticize Flock Safety. That’s textbook fair use.

The EFF saw it for what it was: a SLAPP-style threat designed to scare a solo developer into shutting down. They took Freeman’s case pro bono and fired back a response that essentially told Flock to get lost ^[3].

But it got worse. Flock Safety’s CEO, Garrett Langley, referred to DeFlock as a “terroristic organization.” A billion-dollar surveillance company called a guy with a website a terrorist for telling people where the cameras are. Let that sink in.

Freeman didn’t back down. Across Colorado and elsewhere, residents have begun filing public-records requests and lawsuits seeking the data Flock cameras collected on their own vehicles ^[5]. If you’re going to call someone a terrorist, you probably shouldn’t have also been surveilling them without a warrant.

The Cancel Wave: 50+ Cities Pull the Plug

DeFlock cracked the dam. Once communities could see how many cameras surrounded them, and once reporters started digging into what police were actually doing with the data, the political calculus shifted.

At least 50 cities have now canceled their Flock contracts, deactivated cameras, or rejected proposals to install them ^[6]. The reasons vary, but they cluster around three themes:

Immigration enforcement fears: After Trump’s deportation crackdown escalated in early 2026, sanctuary cities realized Flock data could flow to ICE. Residents demanded answers. Some cities couldn’t guarantee the data wouldn’t be shared ^[6].
Warrantless mass surveillance: The ACLU and EFF filed suit in Santa Clara County on behalf of SIREN and CAIR-CA, challenging San Jose’s practice of letting police search Flock data without a warrant. The city has nearly 500 cameras stationed near clinics, immigration centers, and places of worship ^[7].
Documented racial profiling: EFF’s analysis of Flock audit logs found 80+ law enforcement agencies using Romani stereotypes in searches (terms like “g*psy vehicle,” “possible g*psy,” “roma traveler”) often with no crime mentioned ^[8]. Another 400+ searches targeted Irish Traveller communities.

Verona, Wisconsin became a poster child for the movement when residents successfully pressured the city to end its Flock contract outright ^[9]. In San Francisco, activists showed up at Lowe’s shareholder meeting demanding the company stop hosting Flock cameras on its properties ^[10]. NPR, TechCrunch, The New Republic, KQED: national outlets started paying attention.

Five States, Physical Destruction

Some people decided mapping the cameras wasn’t enough.

In at least five states, residents have physically destroyed Flock cameras: cutting them down from poles, smashing the solar panels, ripping them off signs ^[4]. TechCrunch reported the trend in February 2026, and it’s continued since.

This is not something we endorse. Destroying infrastructure is illegal and gives Flock’s PR team ammunition. But it tells you something about the depth of anger when ordinary people decide a camera on their street is worth the felony risk.

The irony: Flock’s cameras are supposed to make communities safer. But the communities don’t feel safe from the cameras.

The EFF Report: “We’re Winning”

On June 2, 2026, the EFF published “We’re Fighting Mass Surveillance Tech and Winning,” a comprehensive accounting of their multi-year investigation into Flock Safety ^[2]. The numbers are staggering:

Tens of thousands of cameras mapped by DeFlock’s crowdsourced network
80+ police agencies caught using anti-Romani slurs in Flock searches
50+ cities that have canceled, deactivated, or rejected Flock
Multiple lawsuits challenging warrantless searches in California and Colorado
50+ agencies that used Flock to track protesters

The EFF titled the piece “We’re Fighting Mass Surveillance Tech and Winning.” For once, the optimism seems earned.

Their investigation found that without warrant requirements, police use Flock for virtually anything: school residency verification, noise complaints, background checks, immigration sweeps ^[11]. The technology was sold as a tool to solve violent crime. It became a tool for everything police want to do but can’t justify a warrant for.

States Start Legislating

Washington state moved first on the legislative front. The Municipal Research and Services Center documented new restrictions on Flock cameras at the state level, with municipalities gaining explicit authority to reject or restrict deployments ^[12].

Colorado is watching closely. Boulder residents filed their own lawsuit against the police department over Flock surveillance in May 2026 ^[5]. The Colorado Sun documented how grassroots movements across the state are pushing back against the spread of AI-powered license plate readers ^[13].

The legislative battles are just starting. But the political ground has shifted. Two years ago, a city council voting to install Flock cameras was a rubber-stamp process. Now it’s a fight. That’s DeFlock’s real victory.

What You Can Do

Check DeFlock’s map: Visit deflock.org to see how many ALPR cameras are near your home, workplace, school, or place of worship. Report cameras you find that aren’t mapped yet.
Ask your city council: Does your city have a Flock contract? What are the data retention policies? Can police search without a warrant? Who else gets access to the data? Some cities don’t even know the answers.
File records requests: In states with strong public records laws, you can request audit logs showing how police use Flock searches. The EFF’s investigations began with exactly these requests.
Support the legal fights: The EFF and ACLU are funding the lawsuits that will set precedent on whether mass plate surveillance requires warrants. These cases matter.
Talk to your neighbors: Most people don’t know these cameras exist, let alone that they’re tracking every car on the street. Awareness is step one. DeFlock proved that.
