Background
Between November 5 and November 29, 2023, Norfolk, Virginia experienced a series of commercial burglaries occurring in the early morning hours. Three confirmed burglaries targeted Nu Beauty Supply, George’s Seafood, and Quick Serve. The Quick Serve burglary resulted in the theft of lottery tickets. Later that morning, when someone attempted to cash one of the stolen tickets at Miller’s Store, Virginia Lottery investigator Adam Hankins reviewed surveillance footage and shared photographs with Norfolk Police, including a still image of a white BMW SUV with distinctive black rims.
Detective Kevin Gross accessed the Flock automatic license plate reader system—a network of 172 cameras installed at Norfolk intersections that capture vehicle images and license plate data, stored for 30 days—searching for the white BMW SUV in the vicinity of Miller’s Store during the relevant two-hour window. The Flock system returned one match showing the BMW with black rims and its license plate. Through a Virginia Department of Motor Vehicles database search using the recovered license plate number, Detective Gross identified Eddie Eugene Robinson as the vehicle’s registered owner. The photo of Robinson matched the person depicted in Quick Serve burglary surveillance footage. Police obtained an arrest warrant and, upon executing a search warrant at Robinson’s home, discovered stolen lottery tickets, checks from George’s Seafood, beauty products from Nu Beauty Supply, and a firearm.
Robinson moved to suppress all evidence obtained through the Flock database search, arguing it constituted a warrantless Fourth Amendment violation. The trial court denied the motion, and Robinson appealed after entering conditional guilty pleas to three felonies for statutory burglary, larceny of lottery tickets, grand larceny, and possession of a firearm by a nonviolent felon.
The Court’s Holding
The Court of Appeals held that police did not violate the Fourth Amendment by accessing the Flock system without a search warrant. The court’s analysis centered on whether Robinson possessed a “reasonable expectation of privacy” in the data collected by the license plate readers. As a threshold matter, the court noted that Robinson had no reasonable expectation of privacy in his vehicle’s physical characteristics—its color, manufacturer, model, and identifying features—or its license plate as he drove it on public streets. Because the vehicle’s exterior and license plate were “voluntarily conveyed to anyone who wanted to look,” the Flock cameras merely augmented police officers’ natural sensory abilities rather than intruding upon protected privacy interests.
The court distinguished the Flock system from more invasive surveillance technologies addressed in precedent. In Carpenter v. United States (2018), the U.S. Supreme Court required a warrant to access 127 days of cell-site location information showing an individual’s comprehensive movements throughout private spaces. In Leaders of a Beautiful Struggle v. Baltimore Police Department (4th Cir. 2021), the Fourth Circuit struck down aerial surveillance that tracked persons and vehicles across 90 percent of Baltimore for twelve hours daily over 45 days. By contrast, the Flock system captures only still images of vehicles’ exteriors on public roads, retains data for merely 30 days, does not track continuous movement, and provides no “intimate window” into Robinson’s personal habits, associations, or activities. The cameras photograph vehicles, not persons, and yield information already publicly visible.
The court emphasized its decision rested on the specific facts of the current Flock system in Norfolk and declined to speculate whether future technological enhancements might create such comprehensive movement chronicles as to trigger Fourth Amendment protection. Accordingly, Detective Gross lawfully accessed the Flock database to identify Robinson’s vehicle and obtained the license plate information needed to complete the investigation.
Key Takeaways
- License plate readers monitoring public roads do not implicate Fourth Amendment search protections when they capture only publicly visible vehicle exterior and plate information.
- Reasonable expectation of privacy analysis is fact-specific and depends on the scope, scale, and duration of surveillance—not merely its technological sophistication.
- Automatic license plate readers are constitutionally distinguishable from cell-site location tracking or comprehensive aerial surveillance of population movements.
- Police need not obtain a warrant to access license plate reader databases for vehicle identification in criminal investigations.
Why It Matters
This decision clarifies Fourth Amendment protections in the age of emerging automated surveillance technologies. As law enforcement agencies increasingly deploy automatic license plate readers and similar systems, Robinson establishes that such tools do not require judicial oversight through the warrant requirement—a significant ruling that favors police investigative efficiency. The decision also suggests a framework courts may apply to future surveillance technologies: intrusions into reasonable expectations of privacy depend not on technology itself but on whether the data collected exceeds information naturally available to the public.
However, the court’s explicit reservation—that it reaches no conclusion about future Flock enhancements or larger-scale systems—leaves open the possibility that dramatically expanded license plate reader networks or longer data retention periods might cross into territory requiring constitutional protection. For law enforcement and municipalities considering license plate reader deployment, the ruling removes a significant legal barrier while courts and legislatures continue debating appropriate limits on automated surveillance.
