United States v. Hay
95 F.4th 1304 (10th Cir. 2024) · Cert. denied Nov. 25, 2024
A comprehensive legal monograph on 68 days of near-constant warrantless pole-camera surveillance of a home, the public-view doctrine, Carpenter’s “whole of movements” rationale, the home, retrospective versus prospective monitoring, and the implications for modern camera networks, RTCCs, ALPR, drones, and AI-assisted surveillance.
Executive Summary
United States v. Hay is one of the most important post-Carpenter federal appellate decisions on long-term pole-camera surveillance of a home. The Tenth Circuit held that the Department of Veterans Affairs did not conduct a Fourth Amendment search when investigators used a remote, motion-activated camera to record the publicly visible front of Bruce Hay’s residence for sixty-eight days. The system captured roughly fifteen hours of footage per day and created an extensive record of Hay’s activity outside his home.
The case arose from a lengthy investigation into suspected disability-benefits fraud. Hay was a U.S. Army veteran who had been diagnosed with functional neurological disorder after a serious automobile accident. The VA determined in 2006 that he was permanently disabled and entitled to lifetime benefits. Six years later, the VA Inspector General received an anonymous tip alleging that Hay was exaggerating his disability. Investigators began a multi-year effort to compare the severe limitations he reported to the VA with his actual daily functioning.
Agents used several investigative techniques. They followed Hay to medical appointments and other events and even staged an apparent deer-poaching operation on a nearby farm to create an opportunity for closer observation. To obtain a more complete record of his ordinary daily activity, the VA installed a pole-mounted camera on a school rooftop across the street from his home in Osawatomie, Kansas.
The camera was remote-controlled and motion-activated. It captured near-constant video of Hay’s home as visible from the street—approximately fifteen hours per day for sixty-eight days. Investigators used the footage to show that Hay’s actual mobility differed materially from the limitations he represented during disability evaluations. The investigation ultimately led to an indictment for stealing government property and wire fraud, and a jury convicted him on all counts.
On appeal, Hay argued that months of constant video surveillance of his home constituted a search under emerging Supreme Court Fourth Amendment doctrine, particularly Carpenter v. United States. The Tenth Circuit rejected that argument and affirmed.
The court’s analysis began with existing circuit precedent. In United States v. Jackson, the Tenth Circuit had upheld covert video surveillance of a residence where cameras captured only what members of the public could see. Although Jackson predated Carpenter, the Hay panel concluded that Carpenter had not abrogated it.
The first step was the familiar public-view rule. Hay’s camera could only observe his property as visible from across the street. The panel noted that the camera incidentally captured some nighttime activity inside the house through a window, but that activity itself was visible to any passerby. Because the camera did not expose anything that was not already in public view, the court concluded the surveillance fit comfortably within the conventional rule that officers need not “shield their eyes” from what can be seen from public thoroughfares.
Hay’s stronger argument concerned aggregation. Sixty-eight days of recurring video can reveal habits, visitors, routines, associations, and patterns in a way that a single drive-by observation cannot. He relied on Carpenter’s protection of “the whole of [a person’s] physical movements” and argued that the accumulated home-surveillance record should receive similar protection.
The Tenth Circuit distinguished Carpenter on two grounds. First, the pole camera did not come close to capturing the whole of Hay’s movements. It recorded only one location—the front of his house. Once Hay left, the camera could no longer track him. Historical CSLI, by contrast, can reveal where a person travels across many locations.
Second, the court emphasized the prospective character of the investigation. Carpenter was especially concerned about law enforcement’s ability to query a preexisting database and “travel back in time” to reconstruct a person’s prior whereabouts. The VA did not obtain an archive that had already been created for another purpose. Investigators installed the camera after Hay had become a suspect and used it prospectively to monitor activity that they could otherwise have watched from the street.
The panel also considered the heightened Fourth Amendment protection of the home. It recognized that “the home is first among equals,” but concluded that the special status of the home did not create privacy in activities exposed to public view. Under California v. Ciraolo and Kyllo v. United States, the constitutional problem becomes much stronger when government uses technology to reveal details that ordinary public observation could not reveal. Hay’s camera did not do that.
The court surveyed the emerging pole-camera caselaw and found substantial federal appellate support for its conclusion. It cited United States v. Tuggle, which upheld nearly eighteen months of pole-camera surveillance in the Seventh Circuit; United States v. Trice in the Sixth Circuit; and the fractured en banc decision in United States v. Moore-Bush. It also distinguished the Fourth Circuit’s Leaders of a Beautiful Struggle decision because that case involved persistent aerial surveillance capable of reconstructing movements across an entire city.
The opinion contains an important observation about changing technology. The court acknowledged concerns that camera systems are becoming more pervasive and that modern analytical tools can support identification and pattern recognition at a degree once unimaginable. Yet it also observed that as cameras become ubiquitous in society, social expectations of freedom from filming in public may diminish. That observation reflects one of the unresolved tensions of modern privacy law: advancing technology can simultaneously increase government surveillance power and normalize recording in everyday life.
The Supreme Court denied Hay’s petition for certiorari on November 25, 2024. That denial did not endorse the Tenth Circuit’s reasoning, but it left the decision in place. Hay therefore remains an important Tenth Circuit authority governing conventional pole-camera surveillance of areas exposed to public view.
For law-enforcement agencies, Hay provides a relatively clear federal rule in the Tenth Circuit, but its factual boundaries matter. The camera watched the front of one home from a public vantage point. It did not see through walls, defeat a privacy fence, use thermal imaging, identify every visitor through facial recognition, or follow Hay across a broader camera network. It was installed prospectively after investigators had already focused on him.
Those limits become more important as agencies deploy AI. Modern video systems can index months of footage, identify persons and vehicles automatically, correlate visitors across camera networks, and reconstruct movement histories. If software transforms one-location observation into cross-location tracking, the factual premise Hay used to distinguish Carpenter may no longer hold.
Five Key Takeaways
Facts of the Investigation
Bruce Hay served in the U.S. Army. In 2005, he was involved in a serious car accident at home in Kansas. Physicians diagnosed him with functional neurological disorder, which impaired his mobility. He applied for VA disability benefits and in 2006 was deemed permanently disabled.
In 2012, the VA Inspector General received an anonymous tip alleging that Hay was not permanently disabled. Investigators initiated an inquiry into whether he was exaggerating his limitations to continue receiving disability benefits.
Hay lived in Osawatomie, Kansas, a small town in eastern Kansas. Investigators used multiple techniques over roughly six years. They observed Hay at medical visits and at other locations, and they staged a deer-poaching scenario at a nearby farm to create a reason to watch him more closely without revealing the disability-fraud investigation.
To capture ordinary activity at home, the VA installed a camera on a school rooftop across the street. The resulting footage showed a range of activity that investigators believed was inconsistent with the severe mobility limitations Hay reported during VA examinations.
The evidence was not limited to the pole camera. The government presented testimony from investigators and medical professionals and relied on Hay’s own representations to the VA. The discrepancy between reported limitations and observed functioning became central to the prosecution.
The Pole-Camera Technology
Remote controlled
The camera could be operated remotely, reducing the need for continuous physical surveillance near Hay’s home.
Motion activated
The system was motion-activated rather than simply generating meaningless footage around the clock. Even so, it captured approximately fifteen hours of footage each day.
Sixty-eight days
The camera operated for sixty-eight days, producing a substantial record of activity around the front of the residence.
Street-equivalent view
The Tenth Circuit repeatedly emphasized that the camera could only view Hay’s property as visible from across the street.
Incidental interior visibility
Hay noted that the footage incidentally captured some activity inside the house at night through a window. The court treated that activity as publicly visible because a passerby could have seen it from the same vantage point.
Procedural History
Hay suffers serious injuries and is diagnosed with functional neurological disorder.
The VA finds Hay permanently disabled and awards benefits.
The VA Inspector General begins investigating whether Hay is exaggerating his disability.
Agents use physical surveillance, staged investigative activity, medical evidence, and eventually pole-camera monitoring.
The camera records roughly fifteen hours per day from across the street from Hay’s home.
A grand jury charges ten counts of stealing government property and six counts of wire fraud.
Hay is convicted on all counts.
The court affirms, including the district court’s refusal to suppress the pole-camera footage.
Hay petitions the Supreme Court.
The Supreme Court declines review.
Holding
The Tenth Circuit held that Hay had no reasonable expectation of privacy in the camera’s view of the front of his house because the system captured only what was visible from the street. The court rejected the argument that the duration and persistence of the surveillance transformed it into a search.
The court also concluded that Carpenter did not control because the pole camera did not capture the whole of Hay’s physical movements and did not allow investigators to search a preexisting historical database of his whereabouts. It was a prospective investigative tool directed at one known suspect and one location.
The Public-View Doctrine
Hay relies on the long-standing rule that a person generally lacks a reasonable expectation of privacy in activities exposed to public observation. The Supreme Court has repeatedly said officers do not have to “shield their eyes” when passing a home on a public thoroughfare.
The camera’s position across the street was therefore critical. The panel found no evidence that it overcame a privacy barrier or captured concealed details. What it saw was what a passerby could see.
Ciraolo
California v. Ciraolo supported this approach by holding that observation of residential curtilage from a lawful public vantage could fall outside the Fourth Amendment even though the home receives heightened protection.
Kyllo
Kyllo v. United States illustrates the opposite rule: using technology not in general public use to explore details of the home previously unknowable without physical intrusion is a search. Hay’s camera did not do that.
Tenth Circuit Precedent: United States v. Jackson
The Tenth Circuit treated United States v. Jackson as important circuit precedent. Jackson involved covert video cameras monitoring the front and back of a residence. The court had found no search because the cameras captured only what could have been seen through ordinary visual observation.
Hay argued that Carpenter had undermined Jackson. The panel disagreed. It concluded that Carpenter’s concern with historical CSLI did not eliminate the public-view rule governing conventional video surveillance.
The court also rejected the claim that Kyllo altered Jackson because ordinary cameras are widely available to the public and do not fit Kyllo’s concern with uncommon sense-enhancing technology revealing concealed home details.
Carpenter and the “Whole of Movements”
Hay’s central argument was that sixty-eight days of recurring home surveillance created a detailed record of habits, visitors, and patterns and therefore implicated the privacy interest recognized in Carpenter.
The Tenth Circuit rejected the analogy. Carpenter involved historical CSLI that could reveal an all-encompassing record of a person’s whereabouts. Hay’s pole camera could only capture movement at a single location outside the house.
Once Hay left the property, the camera could not track him. That geographic limitation was decisive. The court held that Hay retained privacy in the whole of his physical movements, but the camera did not intrude on that interest.
Prospective Versus Retrospective Surveillance
The Tenth Circuit drew another distinction from Carpenter: retrospective database access versus prospective observation.
Historical CSLI lets police “travel back in time” and retrieve a movement record that already exists, often before the individual became a suspect. In Hay, the government installed the camera after investigators had already targeted him. The surveillance began prospectively and then recorded future events.
The court viewed that distinction as constitutionally relevant because the technique merely enhanced something police could always do—monitor the public-facing activity of a suspect under active investigation.
Modern systems can blur this line. A camera network with years of retained video can be queried retrospectively even if each camera originally recorded prospectively. Agencies should therefore distinguish live deployment from later historical data mining.
The Home and Its Special Constitutional Status
The panel acknowledged that the home receives the Fourth Amendment’s highest protection. But it rejected Hay’s attempt to combine the privacy of the home with Carpenter’s movement-aggregation doctrine to create a new categorical privacy interest in all exterior activity near the residence.
Under Ciraolo, the home’s special status does not require officers to ignore what is visible from the street. Under Kyllo, however, using technology to reveal otherwise unknowable details of the home can trigger the Fourth Amendment.
Hay fell on the public-view side of that line because the camera did not reveal hidden interior activity or defeat a barrier to observation.
Why 68 Days Did Not Change the Result
Sixty-eight days is long enough to reveal patterns. Hay argued that duration converted ordinary observation into a comprehensive surveillance record. The Tenth Circuit concluded that duration alone did not overcome the camera’s limited spatial scope.
The court surveyed other federal appellate decisions and found that no clear federal rule required suppression merely because conventional pole-camera surveillance was prolonged. Tuggle’s eighteen-month surveillance was particularly important support.
The result reinforces a recurring federal distinction: long duration may raise concern, but fixed-location video has generally received less protection than technology that follows a person across many locations.
Comparison with the Major Pole-Camera Cases
| Case | Duration / Scope | Outcome | Key Reason |
|---|---|---|---|
| Houston (6th Cir. 2016) | 10 weeks; rural property | No search | Public view; fixed location |
| Tuggle (7th Cir. 2021) | Nearly 18 months; home exterior | No search | Public view; Carpenter distinguished |
| Moore-Bush (1st Cir. en banc 2022) | About 8 months; home | 3–3 split | Disagreement over Carpenter and aggregation |
| Hay (10th Cir. 2024) | 68 days; front of home | No search | Public view; prospective; one location |
| Leaders of a Beautiful Struggle (4th Cir. en banc 2021) | Citywide aerial record | Search | Retrospective reconstruction of broader movements |
Hay fits the mainstream federal pole-camera approach but offers a particularly explicit distinction between prospective targeted monitoring and retrospective access to a preexisting movement database.
Important Limits of Hay
- The camera saw only what was visible from the street.
- It did not defeat a privacy fence or other visual barrier.
- It did not use thermal imaging or through-wall sensing.
- It remained fixed at one location.
- It did not follow Hay across a network of cameras.
- It was deployed prospectively after Hay became the subject of investigation.
- It did not involve facial recognition or automated re-identification.
- State constitutional law may provide greater protection.
- The Supreme Court’s denial of certiorari did not endorse the reasoning.
Practical Guidance for Law Enforcement
Document public visibility
Photograph or diagram what an ordinary passerby can see from the camera’s location. Hay’s holding depends heavily on the equivalence between the camera view and public observation.
Do not defeat privacy barriers without legal review
A camera deliberately positioned to see over an opaque fence or into an otherwise concealed area presents materially different facts.
Define whether surveillance is prospective or retrospective
Installing a camera for an active investigation is different from searching years of already-retained footage to reconstruct someone’s past. Policy should recognize the distinction.
Inventory advanced features
Facial recognition, person re-identification, cross-camera tracking, infrared, audio, and AI analytics were not part of Hay’s basic rule.
Set duration and renewal checkpoints
Even though 68 days was upheld, prolonged residential monitoring should receive periodic supervisory and legal review.
Control retention
Long-term storage can convert prospective collection into a retrospective surveillance database. Define deletion, case preservation, and historical access rules.
Check state law
State constitutions and statutes may impose standards more protective than federal Tenth Circuit doctrine.
Consider judicial authorization where facts move beyond Hay
For unusual duration, concealed vantage points, advanced analytics, or networked tracking, obtaining a warrant can materially reduce litigation risk.

AI and Video-Analytics Implications
Hay’s constitutional reasoning depends heavily on the idea that one stationary camera watches one place. Artificial intelligence can erode that premise.
Automated object indexing
AI can identify every person, vehicle, package, arrival, departure, or recurring event in months of footage. This turns passive video into a searchable database.
Facial recognition
Automated face matching can identify visitors instantly or retrospectively. Hay did not consider population-scale identification.
Person re-identification
Software can infer that the same person appears across different camera feeds using gait, clothing, body shape, timing, and contextual features. That creates cross-location continuity without a face match.
Behavioral and association analysis
AI can detect recurring visits, repeated co-presence, routines, and interaction patterns. These derived inferences may be more revealing than individual public observations.
Historical natural-language search
Multimodal systems can make months of footage queryable through ordinary language. A user could ask for every recurring visitor, every truck appearing after dark, or all occasions when a particular person entered the scene.
Spatial reach becomes decisive
If AI links Hay-style cameras across a network, the system may begin to reconstruct the “whole of movements” the Tenth Circuit said the single pole camera could not capture.
Real-Time Crime Centers and ALPR
RTCC systems can merge fixed cameras with ALPR, CAD, drones, gunshot detection, mapping, and other datasets. That integration can convert a local observation into a regional movement record.
ALPR linkage
A vehicle observed outside a home can be identified through ALPR and then traced through historical plate sightings. That combined analysis reaches beyond Hay’s one-location footage.
Retrospective search
Modern RTCC systems may contain years of stored video and vehicle data. Querying those archives later begins to resemble the retrospective capability that Hay distinguished from its prospective pole-camera deployment.
Governance
Agencies should log historical queries, limit access to legitimate law-enforcement purposes, control retention, and require enhanced review for pattern-of-life analysis.
Drones and Aerial Surveillance
Hay does not resolve drone surveillance. Drones can provide different vantage points, including views unavailable from the street. They can also use thermal sensors, high-powered zoom, and automated tracking.
Short event-specific flights are materially different from persistent residential monitoring. DFR programs should separately evaluate historical retention, AI tracking, and integration with fixed-camera and ALPR networks.
Future Litigation
Historical camera databases
A major future question is whether searching years of preexisting public-camera footage is constitutionally different from installing a camera prospectively after a suspect is identified.
Cross-camera tracking
If software follows an individual across many public cameras, the resulting record may approach Carpenter’s whole-of-movements concern.
Facial recognition and identity search
Historical face queries can transform public-camera archives into a database of where a person appeared over time.
Privacy fences and hidden areas
Cases involving cameras intentionally positioned to see over effective privacy barriers may present stronger Fourth Amendment claims than Hay.
State constitutional law
State courts may continue to depart from the federal approach and require warrants for prolonged home surveillance.
Chatrie’s influence
Chatrie’s emphasis on precise retrospective location information may strengthen future arguments that highly searchable video archives deserve protection even when individual images were captured in public.
Frequently Asked Questions
Did Hay hold that police can record a home indefinitely without a warrant?
No. It upheld 68 days of surveillance on specific facts involving a public-facing view, one fixed location, and conventional camera technology.
Does Carpenter overrule Hay?
No. The Tenth Circuit expressly distinguished Carpenter.
Why did the court distinguish Carpenter?
The camera did not capture the whole of Hay’s movements and was deployed prospectively rather than used to search a preexisting historical movement database.
Does the home still receive special protection?
Yes. But the court held that the home’s special status does not create privacy in activity exposed to public observation.
What if a camera sees over a privacy fence?
That presents different facts and a stronger Fourth Amendment argument.
What if the system uses facial recognition?
Hay did not address facial recognition. Automated identification can materially change the surveillance capability.
Did the Supreme Court approve Hay?
No. The Supreme Court denied certiorari on November 25, 2024. Certiorari denial is not an endorsement.
Should agencies still consider a warrant?
Yes, particularly where surveillance is unusually prolonged, technologically enhanced, hidden from ordinary public view, or integrated across multiple systems.
Instructor and Training Notes
Teaching objective 1: Spatial scope versus duration
Ask students which is more intrusive: 68 days watching one home or two hours tracking a person across many sensitive locations. Hay and Chatrie make the comparison useful.
Teaching objective 2: Prospective versus retrospective
Have students distinguish installing a camera today from searching a five-year video archive tomorrow.
Teaching objective 3: Public view versus home privacy
Use Hay with Ciraolo and Kyllo to show that the home receives special protection without creating a blanket shield over everything visible from the street.
Teaching objective 4: Add AI
Add face recognition or cross-camera tracking and ask whether the same constitutional rationale remains persuasive.
Teaching objective 5: Compare federal approaches
Pair Hay with Tuggle, Moore-Bush, Houston, and Leaders of a Beautiful Struggle to show the evolving federal surveillance framework.
Shield Practice Notes
- Hay is strongest when the camera sees only what the street exposes.
- Duration alone was not dispositive.
- Spatial comprehensiveness mattered more than the number of days.
- Prospective surveillance was a key distinction from Carpenter.
- The home remains highly protected, but public-facing activity may still be observed.
- Do not assume Hay covers cameras positioned to defeat privacy barriers.
- Facial recognition and automated re-identification were not before the court.
- Historical video mining can look more like Carpenter than the original Hay deployment.
- RTCC and ALPR integration may erase the one-location limitation.
- State law may impose more protective rules.
- Cert denial is not Supreme Court approval.
- For prolonged residential surveillance outside Hay’s facts, consider a warrant.
