License Plate Readers Tracking Americans on the Road

​Katie King in the Virginian-Pilot reports an in-depth account about the growing dependency of local law enforcement agencies on Flock Safety cameras, mounted on roads and intersections to catch drivers suspected of crimes. With more than 5,000 police agencies across the nation using these devices, the privacy implications are enormous.
 
Surveillance cameras have been in the news at lot lately, often in a positive light. Local news is consumed by murder suspects and porch pirates alike captured on video. The recently released video of a physical attack by rapper Sean “Diddy” Combs on a girlfriend several years ago has saturated media, reminding us that surveillance can protect the vulnerable. The crime-solving potential of license plate readers is huge. Flock’s software runs license plate numbers through law enforcement databases, allowing police to quickly track a stolen car, locate suspects fleeing a crime, or find a missing person. With such technologies, Silver and Amber alerts might one day become obsolete.
 
As with facial recognition technology, however, license plate readers can produce false positives, ensnaring innocent people in the criminal justice system. King recounts the ordeal of an Ohio man who was arrested by police with drawn guns and a snarling dog. Flock’s license plate reader had falsely flagged his vehicle as having stolen tags. The good news is that Flock insists it is not even considering combining its network with facial recognition technology – reducing the possibility of both technologies flagging someone as dangerous.
 
As with so many surveillance technologies, the greater issue in license-plate readers is not the technology itself, but how it might be used in a network.
 
“There’s a simple principle that we’ve always had in this country, which is that the government doesn’t get to watch everybody all the time just in case somebody commits a crime – the United States is not China,” Jay Stanley, a senior analyst with the American Civil Liberties Union, told King. “But these cameras are being deployed with such density that it’s like GPS-tracking everyone.”
 
License plate readers could, conceivably, be networked to track everywhere that everyone goes – from trips to mental health clinics, to gun stores, to houses of worship, and protests.
 
With so many federal agencies already purchasing Americans’ sensitive data from data brokers, creating a national network of drivers’ whereabouts is just one more addition to what is already becoming a national surveillance system. With apologies to Jay Stanley, we are in serious danger of becoming China. As massive databases compile facial recognition, location data, and now driving routes, we need more than ever to head off the combination of all these measures. A good place to start would be for the U.S. Senate follow the example of the House by passing the Fourth Amendment Is Not For Sale Act.
