Eleventh Circuit Reaffirms: Police-Activated Lights Can Still Be a Consensual Encounter, and Oliver’s “Open Fields” Doctrine Remains Binding

1. Introduction

In United States v. Jesse Rance Moore (11th Cir. Mar. 13, 2026) (unpublished), the Eleventh Circuit affirmed convictions arising from the armed robbery of three Florida pharmacies: one count of conspiracy to commit robbery, three robbery counts, and three counts of brandishing a firearm during a crime of violence (18 U.S.C. §§ 1951, 924(c)).

The appeal focused on suppression issues under the Fourth Amendment. Mr. Moore argued that:

  • His encounter with Officer Nigel Elliott amounted to an investigatory stop unsupported by reasonable suspicion or probable cause.
  • Officers later entered his property without a warrant or consent, and the “open fields” doctrine should not validate the entry.

The Eleventh Circuit rejected both challenges, holding (1) the roadside interaction was a consensual encounter, and (2) the later entry occurred on an undeveloped lot qualifying as “open fields” under binding Supreme Court precedent.

2. Summary of the Opinion

The court affirmed the denial of Mr. Moore’s suppression motions. It held:

  1. No seizure occurred during Officer Elliott’s brief contact; under the totality of circumstances, a reasonable person would have felt free to terminate the encounter.
  2. The officers’ later warrantless entry onto Mr. Moore’s semi-wooded, undeveloped property did not implicate the Fourth Amendment because it fell within the “open fields” doctrine; arguments that later Supreme Court cases “undermined” that doctrine could not overcome the continued binding force of Oliver v. United States.

3. Analysis

A. Precedents Cited

(i) Standards of review and deference

  • United States v. Perez, 443 F.3d 772 (11th Cir. 2006): The court relied on Perez for the “mixed question of law and fact” framework on suppression and for the taxonomy of police-citizen encounters (consensual encounters; investigatory stops; arrests).
  • United States v. Holmes, 141 F.4th 1183 (11th Cir. 2025): Cited for plenary review of legal conclusions and clear-error review of factual findings, with facts viewed in the prevailing party’s favor.
  • United States v. Holt, 777 F.3d 1234 (11th Cir. 2015): Cited for deference to credibility determinations.
  • Cooper v. Harris, 581 U.S. 285 (2017): Used to reinforce clear-error deference—if the district court’s factual finding is plausible, it controls even if another view is also plausible.

(ii) Fourth Amendment baseline rules and the exclusionary rule

  • Brigham City, Utah v. Stuart, 547 U.S. 398 (2006): Cited for the general proposition that the Fourth Amendment shields against unreasonable searches and seizures subject to exceptions.
  • Mapp v. Ohio, 367 U.S. 643 (1961): Cited for the exclusionary rule—unconstitutionally obtained evidence is generally inadmissible.
  • Wong Sun v. United States, 371 U.S. 471 (1963): Cited for “fruit of the poisonous tree,” extending suppression to derivative evidence obtained by exploitation of illegality.

(iii) Consensual encounters vs investigatory stops

  • United States v. Knights, 989 F.3d 1281 (11th Cir. 2021): Central to the holding. The court used Knights for the objective test: whether a reasonable innocent person would feel free to terminate the encounter, and for the relevance of factors such as blocking a path, number of officers, display of weapons, commands, tone, and requests for identification. The court also analogized Knights to hold that parking close to a car and approaching—without commands, weapons, touching, or ID requests—can remain consensual.

(iv) Open fields, curtilage, and property-based Fourth Amendment doctrine

  • Oliver v. United States, 466 U.S. 170 (1984): The binding foundation. The court treated Oliver as dispositive that open fields (including privately owned, undeveloped land beyond the home’s immediate area) are not protected by the Fourth Amendment, and that fences and “No Trespassing” signs do not create a legitimate expectation of privacy in an open field.
  • United States v. Taylor, 458 F.3d 1201 (11th Cir. 2006): Applied to define open fields as “any unoccupied or undeveloped area beyond the immediate domestic establishment of the home,” and to emphasize that constitutional protection attaches to the residence and area immediately surrounding it, not to open fields.
  • Florida v. Jardines, 569 U.S. 1 (2013): Cited both for the residence/curtilage distinction and—importantly—to rebut Moore’s “undermined” argument by quoting Jardines’ explicit acknowledgement that officers may gather information in “open fields.”
  • Katz [v. United States, 389 U.S. 347 (1967)]: Mentioned via Jardines as part of the analytic backdrop for when information-gathering on private property implicates Fourth Amendment protections (expectation-of-privacy concepts).

B. Legal Reasoning

(i) The encounter with Officer Elliott was consensual

The court accepted the magistrate judge’s factual findings (grounded in credibility determinations) that Officer Elliott stopped because he thought a couple was arguing and wanted to prevent escalation—not to detain them for the robbery investigation. The key operational facts for the court’s Fourth Amendment analysis were that Officer Elliott:

  • Activated lights (no siren) to identify himself as law enforcement.
  • Did not draw a weapon, issue commands, touch anyone, or request identification.
  • Did not mention the robbery or ask investigatory questions about it.
  • Left the scene, and only then did Mr. Moore approach and flag him down.
  • Parked such that there was space to maneuver out (or by removing the cable across posts).

Applying United States v. Knights and the factors articulated in United States v. Perez, the court concluded an objective reasonable person would have felt free to terminate the interaction. Therefore, no “seizure” occurred; reasonable suspicion or probable cause was not required. Moore’s argument that his car was effectively blocked failed because it depended on disputing fact findings reviewed only for clear error, and the court invoked Cooper v. Harris to emphasize that “plausible” findings govern.

(ii) The warrantless entry onto the property was permissible under open-fields doctrine

The court treated the later entry as occurring on a “semi-wooded and undeveloped lot” with no home or structure. On those facts, the Eleventh Circuit agreed that the area was not curtilage and instead constituted an “open field” under Oliver v. United States and United States v. Taylor. As a result, Fourth Amendment protections did not attach, and the entry—however characterized as a “trespass” under state property concepts—did not trigger exclusion of resulting information on Fourth Amendment grounds.

Addressing Moore’s argument that later Supreme Court cases have “called into question” Oliver, the court’s reasoning was institutional as much as doctrinal: unless and until the Supreme Court overrules Oliver, the Eleventh Circuit must apply it. The panel further reinforced this by pointing out that Florida v. Jardines itself expressly acknowledges the continuing vitality of the open-fields doctrine.

C. Impact

(i) Practical guidance for suppression litigation in the Eleventh Circuit

  • Police lights are not automatically a seizure: This decision reinforces that activating lights—especially without siren, commands, weapons, or investigative questioning—can still be consistent with a consensual welfare-check style encounter, depending on whether the person’s freedom to leave is objectively restrained.
  • Clear-error review is often decisive: Where suppression hinges on scene dynamics (blocking a vehicle, tone, commands), the defendant faces a steep challenge on appeal if the district court credited the officer’s account and made “plausible” findings.
  • Open fields remains a bright line for undeveloped land: For rural or undeveloped property without a home/curtilage features, this case underscores that Fourth Amendment suppression arguments will often fail under Oliver/Taylor, even if officers entered without consent and even if signage or barriers exist.

(ii) Doctrinal implications

The opinion is principally an application (not an expansion) of existing doctrine, but it illustrates a continuing trend: courts will reconcile newer property-based Fourth Amendment cases (like Jardines) with Oliver by treating curtilage as protected and open fields as categorically unprotected—leaving any rethinking of open fields to the Supreme Court.

4. Complex Concepts Simplified

  • Consensual encounter vs. investigatory stop: A consensual encounter is a voluntary interaction; the Fourth Amendment is not implicated because the person is free to end the conversation. An investigatory stop (a “Terry stop”) is a brief detention; it requires reasonable suspicion.
  • “Free to leave” test: Courts ask whether a reasonable innocent person would feel free to end the encounter—looking to practical signals like commands, weapons, blocking movement, or demands for ID.
  • Curtilage: The area immediately surrounding a home (like a yard or porch area) that is treated as part of the home for Fourth Amendment purposes.
  • Open fields doctrine: Under Oliver, undeveloped land beyond the home’s immediate area is not protected by the Fourth Amendment, even if privately owned and even if the owner posts “No Trespassing” signs or erects barriers.
  • Fruit of the poisonous tree: If police violate the Fourth Amendment, not only the directly seized evidence but also later-derived evidence can be excluded— unless it came from an independent lawful source or the connection is sufficiently attenuated.

5. Conclusion

United States v. Jesse Rance Moore reaffirms two durable Fourth Amendment principles in the Eleventh Circuit: (1) under a totality-of-circumstances approach, a police interaction—حتى with activated lights—may remain consensual absent objective restraints on a person’s ability to leave; and (2) the “open fields” doctrine of Oliver v. United States remains binding, insulating warrantless information-gathering on undeveloped land outside curtilage from Fourth Amendment suppression remedies. The decision’s broader significance lies less in doctrinal novelty than in its reminder that suppression outcomes often turn on (a) trial-level credibility findings and (b) the continued force of categorical Supreme Court rules that lower courts must apply until explicitly overruled.
