Flock Safety's $8.3B Surveillance Network Faces Mounting Backlash

Flock Safety's network of more than 70 solar-powered cameras helped Providence police identify a gray Nissan with Florida plates within hours of the December 13 Brown University shooting that killed two and wounded eight, according to police records and the company.

The cameras logged the suspect's vehicle 14 times between December 1 and the day of the attack, allowing investigators to trace him to a New Hampshire storage unit in under a week. "We were able to find the vehicle on Flocks, actually get the actual plate, learn that it was a car rental," the Providence police chief told NBC Boston.

That same month, in Haines City, Florida, Officer Christopher Goodson used the same network for a different purpose: tracking his estranged wife. He logged more than 700 unauthorized queries between September 2024 and June 2026 before his arrest, Fox 13 reported.

What does the backlash look like?

The Brown case and the Goodson arrest sit at opposite ends of a story that has turned Flock Safety into one of America's most contested startups. The Atlanta-based company has spent nine years building what critics call the most pervasive vehicle surveillance network in U.S. history, now operating in more than 5,000 communities across 49 states.

Residents have responded with electric saws, paint, and at least one lawn chair. Flock cameras have been vandalized in 36 states, NPR reported. A man in San Diego dressed as Darth Vader appeared at a city council meeting last week to "praise" the network. The San Francisco Standard found 82 Flock contracts terminated across 28 states between August 2021 and May 2026, with 39 terminations in the first five months of 2026 alone.

Boston, Flagstaff, and Santa Clara suspended or ended their contracts in March after Amazon's Ring pulled its Flock integration. The company says it is adding customers at 10 times the rate of churn.

How big is the business?

Flock is now worth $8.3 billion, up from $3.5 billion at its Tiger Global-led Series E in February 2022 and $7.5 billion in March 2025. In April, the company told Fortune it had raised $500 million at the latest valuation, bringing total funding to $1.2 billion. Flock crossed $500 million in annual recurring revenue in the first half of 2026, with over half of new revenue coming from products beyond license-plate readers.

Backers include a16z, Tiger Global, Greenoaks, Sands Capital, Founders Fund, Kleiner Perkins, and Y Combinator. Neither a16z nor Tiger Global responded to requests for comment.

CEO Garrett Langley, an electrical engineer who founded the company after a string of Atlanta-area break-ins, framed the business in mission terms. "Every day, Flock helps solve crimes that would otherwise go unsolved," he said. "From finding missing children, to solving murders, violent crime, and recovering stolen vehicles, Flock gives investigators leads they didn't have before."

How long is the data kept?

Flock's published evidence policy states a 30-day retention standard. Last week, the company recommended a default of seven days and introduced "Evidence Mode" for active cases.

A July audit by the LAPD inspector general found at least one Flock contract that lets the company keep data for five years and use it "for any purpose in Flock's sole discretion." Another contract grants rights to use anonymized footage for "training of machine learning algorithms." That is 60 times longer than the 30-day standard and more than 260 times longer than the newly promoted seven-day figure.

"The real retention period for that city is whatever its own contract says," Tom Bowman, policy counsel at the Center for Democracy and Technology, told Fortune. "This is just a recommendation. This is not legally binding."

Langley pushed back on ABC7: "A car drives by, we take a picture. It's a static picture of a car, and then we read the license plate. That's what the technology is."

Can officers in one city search another city's data?

Yes, and that is the fear. Once a department has a Flock contract, it can query data collected by other agencies, building what Access Now's Michael De Dora called "a searchable, shareable historical database of the whereabouts of Americans."

The Institute for Justice has logged more than 150 documented cases of misuse, including a May 2025 nationwide search by a Johnson County, Texas, sheriff's deputy for a woman suspected of having had an abortion. A Wisconsin officer, according to released court records, searched for a man because his "vehicle travels to Michigan frequently which is a known source state for marijuana."

Is there a legal path forward?

Courts have long held that drivers on public roads have no reasonable expectation of privacy. Anne Toomey McKenna, a visiting law professor at the University of Richmond, said that no longer holds. "Our Fourth Amendment was not designed for the persistent and pervasive surveillance environment which we live [in]," she said.

Bowman pointed to this year's Chatrie v. United States decision, which held that accessing precise location history is a search requiring a warrant regardless of scope. The Fourth Amendment's Not For Sale Act, which would require warrants before police could buy ALPR location data, has been introduced in multiple Congresses and repeatedly blocked.

For Flock, the next 12 months will test whether investor-backed growth can outrun the legal, legislative, and street-level pushback now reshaping how American cities license their public spaces to private surveillance vendors.
