Robinson v. Commonwealth | Flock ALPR Search Analysis

Executive Summary

Why this case matters

Robinson is published state appellate authority applying Knotts, Carpenter, and Leaders of a Beautiful Struggle to a police search of a modern Flock ALPR database.

After surveillance video showed a distinctive white BMW near the attempted redemption of stolen lottery tickets, a detective searched two nearby Flock cameras over a two-hour period. The system returned an image revealing the vehicle’s plate. DMV records identified Eddie Robinson as the registered owner, and later warrants produced evidence connecting him to several burglaries.

The Virginia Court of Appeals held that the database search was not a Fourth Amendment search. Robinson had no reasonable expectation of privacy in the exterior characteristics and plate of his vehicle on public roads. The limited query did not continuously monitor his movements or create the comprehensive personal chronicle at issue in Carpenter.

Norfolk’s Flock System

Norfolk had installed 172 cameras at intersections on public roadways. The cameras captured still images of vehicles and plates and recorded information including plate number, color, make, model, and visible characteristics such as roof racks or bumper stickers.

The information was stored for 30 days. Detectives could query particular locations and timeframes. The court described the system as generally unable to track a vehicle in real time.

The Investigation

Several Norfolk businesses were burglarized during early-morning hours in November 2023. After stolen lottery tickets were presented at a gas station, an investigator reviewed store surveillance and identified a white BMW SUV with black rims. The video did not reveal the license plate.

Knowing that two Flock cameras were near the store, a detective searched for the vehicle’s make and model and limited the query to the two hours surrounding the burglary. The system returned an image of a white BMW with distinctive black rims and revealed its plate.

A DMV query identified Robinson as the registered owner and supplied his photograph. Police obtained an arrest warrant and a warrant to search his home. The home search recovered stolen lottery tickets, checks payable to another burglarized business, merchandise associated with a third business, and a firearm.

Constitutional Question

Did the warrantless, two-hour search of two Flock camera locations for a distinctive vehicle obtain protected location and movement information and therefore constitute a Fourth Amendment search?

Holding

The rule applied

No. On these facts, the Flock search retrieved still images of a vehicle and its publicly displayed plate on public roads. It did not continuously monitor Robinson, reveal private locations, or create a comprehensive chronicle of his movements.

Because the database query was not a Fourth Amendment search, police did not need a warrant to conduct it. The denial of suppression and Robinson’s convictions were affirmed.

Court’s Reasoning

Public Vehicle Characteristics

A driver has no reasonable expectation of privacy in a vehicle’s plate and visible exterior characteristics while traveling on a public street. The court treated the information returned here as something any observer could have seen.

Limited Scope

The detective did not request a long-term movement history. He searched two camera locations within a two-hour window for a vehicle matching known physical characteristics. The query produced a still image of the car on a public highway.

Carpenter Distinguished

The court contrasted Norfolk’s system with 127 days of CSLI averaging 101 data points per day in Carpenter. Flock photographed vehicles rather than continuously following cellphones into homes, offices, medical facilities, and other revealing locations.

Leaders of a Beautiful Struggle Distinguished

The Baltimore aerial-surveillance program covered most of the city for twelve hours per day and enabled reconstruction of movements across time. The limited Flock query did not provide comparable surveillance.

Fact-specific analysis

The court expressly declined to predict when a more capable or comprehensive ALPR network might create a protected chronicle of movement. Its holding was tied to Norfolk’s current system and the narrow search actually conducted.

What the Decision Does—and Does Not—Establish

Do not overread Robinson

The decision concerns a two-hour query associated with two camera locations—not months of historical travel.
The system returned a vehicle image and public plate, not a person’s continuous location.
The court did not announce a categorical rule for every ALPR deployment or database configuration.
It expressly declined to determine when future capabilities might produce a comprehensive chronicle protected by the Fourth Amendment.
The decision does not set a numerical safe harbor based on 172 cameras or a 30-day retention period.
State statutes, other state constitutions, local policy, sharing agreements, and vendor configurations may require a different result.
Identification of a registered owner does not establish who was driving at the time of an observation.

Comparison with Leading Surveillance Decisions

Case	Surveillance Scope	Result
Robinson v. Commonwealth	Two-hour query of two cameras for a distinctive vehicle	No Fourth Amendment search.
United States v. Porter	Periodic LPR observations used to locate a wanted vehicle	No search on the limited facts.
United States v. Mapson	Three historical commercial ALPR observations	ALPR question left open; good faith controlled.
Carpenter v. United States	127 days of detailed CSLI	Protected comprehensive location history.
Leaders of a Beautiful Struggle	Citywide aerial recording permitting retrospective movement reconstruction	Fourth Amendment search.

Agency Guidance

1. Document the query limitsRecord every camera, geographic boundary, time window, vehicle characteristic, and database filter used.

2. Connect scope to known factsExplain why the selected locations, timeframe, vehicle type, and identifying features relate to the offense.

3. Preserve the complete returnRetain all responsive images, metadata, result counts, excluded candidates, search terms, and audit logs.

4. Confirm the plate imageReview the source photograph and do not rely only on OCR-generated characters.

5. Separate owner from driverUse DMV information as a lead and corroborate possession or operation through video, witnesses, or other evidence.

6. Reassess broad searchesExtended histories, dense camera coverage, cross-jurisdictional aggregation, and pattern analysis present greater constitutional risk.

7. Consider legal processWhen a proposed query approaches comprehensive retrospective tracking, consult prosecutors or counsel and consider a probable-cause warrant.

8. Audit system capabilityPolicy should reflect what the deployed network actually can do, including retention, sharing, historical search, analytics, and expansion.
