License Plate-Reading Cameras: A Valuable Tool for Law Enforcement or an Invasion of Privacy?

Introduction to License Plate-Reading Cameras

Hours before the sun rose on Dallas police Chief Daniel Comeaux’s first day on the job, an elderly man in a wheelchair was shot dead near Fair Park. Two days later, the new chief stood among a cluster of officers outside the suspected gunman’s home in west Oak Cliff. He was impressed by one tool the investigators had used to arrive there: the network of license plate-reading cameras scattered across the city.

“I was like, ‘Alright,’” Comeaux recalled saying, referencing the April case months later in an episode of Bridging the Divide, the Assist the Officer Foundation’s podcast, “‘explain this whole Flock camera.’” Investigators tied the suspect to a second fatal shooting earlier the same month. The story, Comeaux said, was one of his favorites to tell. The chief described how the clarity of the vehicle images surprised him and how officers, with those photos in hand, were able to build a case for the arrest.

How License Plate-Reading Cameras Work

The license plate-reading cameras, usually mounted on 12-foot poles, have quickly become standard in police departments across the country, including the Dallas Police Department. Documents recently obtained by The Dallas Morning News through open-record requests indicate Dallas police utilize hundreds of the cameras across the city. The fast-spreading surveillance network is often lauded by investigators, with many crediting the tool as one of their most effective in identifying suspects, making swift arrests and solving crimes.

Civil-liberties advocates are uneasy about the technology’s rise. Those concerns have sometimes turned to action: In Texas, a handful of city and county governments have turned away from Flock Safety, one of the dominant private vendors providing the technology. In those instances, their elected bodies debated the technology’s usages and moved to end or not renew their contracts with Flock Safety.

What is Flock Safety?

Founded in 2017, the Atlanta-based company markets its technology to law enforcement agencies, as well as homeowners associations and private businesses — many of which share their video access with law enforcement.

One of the company’s cofounders, Garrett Langley, told Forbes in an article published in September that they had more than 80,000 AI-powered license-plate cameras across the United States. About 5,000 police agencies use the company’s tools, he told the magazine.

The company markets what it calls its “vehicle fingerprint technology,” a system that doesn’t just read license plates but analyzes a vehicle’s make, model, color and other cosmetics — like bumper stickers or decals — to flag it across a network of cameras. The technology, according to company documents, can identify vehicles with paper tags or no tags at all, search for them without a plate number and match images with scanned vehicles to generate investigative leads.

Concerns About Privacy and Possible Uses

Critics of Flock and other companies’ license plate-reading technology fear the products are being used as part of the Trump Administration’s heightened immigration enforcement efforts. In a June response posted to its website, Flock said local agencies retain discretion over whether or not to share their camera data with federal agencies.

Others, including the American Civil Liberties Union, contend the tool lacks governing rules and have pointed out specific use cases they see as problematic. One such example earlier this year came from Johnson County, southwest of Dallas, where a sheriff’s sergeant used the tool while trying to locate a woman authorities had been told might have had an abortion.

Locations of License Plate-Reading Cameras

Another question is where the cameras are placed. The exact locations are often withheld by police departments, including by Dallas police, in response to inquiries or open records requests.

A crowd-sourced website created by privacy advocates, deflock.me, aims to map Flock cameras around the world and says it has identified more than 58,000 of them.
