Defining the Bounds of Justification Defense and Sentencing Enhancement Burdens in § 922(g)(1) Prosecutions

Introduction

In United States v. Aaron Green, Jr. (11th Cir. 2024), the Court of Appeals for the Eleventh Circuit confronted three major issues arising from a felon-in-possession prosecution under 18 U.S.C. § 922(g)(1):

  • Whether law-enforcement officers lawfully detained and arrested the defendant under the Fourth Amendment, thereby justifying the search that uncovered the firearm;
  • Whether the district court correctly barred the defendant from presenting a self-defense (justification) claim at trial; and
  • Whether the district court properly applied three Sentencing Guidelines enhancements—use of a firearm in connection with another felony, possession of a stolen weapon, and obstruction of justice—when calculating the defendant’s sentence.

Plaintiff-Appellee, the United States, secured a conviction and a 120-month prison sentence. Defendant-Appellant Aaron Green challenged both his conviction and his sentence. The Eleventh Circuit affirmed the conviction, held that the justified-use defense was unavailable because the threat had ended long before the gun was discovered, and found two of the three sentencing enhancements improperly applied. The Court vacated the sentence and remanded for resentencing.

Summary of the Judgment

1. The officers’ stop of Mr. Green on a church lawn two to three hours after a reported shooting at his home was a lawful investigatory detention under Terry v. Ohio. The combination of (a) an earlier shots‐fired call at Green’s address, (b) dispatch information that a victim had arrived at a nearby hospital, and (c) observation of a shiny object on Green’s person furnished reasonable suspicion. When Green disobeyed verbal orders, officers deployed tasers, took him into custody, and—lawfully incident to arrest—seized the firearm.

2. Mr. Green could not assert a justification (self-defense) defense to § 922(g)(1) because he still possessed the gun two hours after the shooting and introduced no evidence of a continuing, imminent threat at the moment of the seizure. Under circuit precedent, justification requires a “present, imminent, and impending threat of death or serious bodily harm.”

3. On sentencing, the district court used three Guidelines enhancements under U.S.S.G. § 2K2.1(b)§4, (b)§6(B), and § 3C1.1. The Eleventh Circuit held:

  • The two-level stolen‐weapon enhancement (§ 2K2.1(b)(4)) was supported by a police report introduced at sentencing and was properly applied.
  • The four-level “firearm-in-connection-with-another-felony” enhancement (§ 2K2.1(b)(6)(B)) lacked a factual predicate proven by a preponderance of the evidence; the government’s attorney representations were not sufficient proof.
  • The two-level obstruction enhancement (§ 3C1.1) also lacked reliable evidentiary support after defense objection and was improperly imposed.
The Court vacated the sentence and remanded for resentencing under the correct Guidelines range.

2. Legal Reasoning

a. Fourth Amendment Detention and Arrest: The Court applied the familiar three-tier framework for police–citizen encounters. Green’s encounter was a brief investigatory stop (Tier 2) properly supported by reasonable suspicion—an objective basis to suspect he participated in a violent shooting and still carried a gun. His refusal to show hands, the reported shell casings at his home, and dispatch information combined to satisfy Terry. Probable cause for assault supported the subsequent arrest and lawful search incident to that arrest.

b. Self-Defense (Justification) Defense: A § 922(g)(1) defendant may invoke necessity/justification only in “extraordinary circumstances.” The four-element test demands proof of (1) present, imminent threat; (2) no reckless self-endangerment; (3) no legal alternative; and (4) direct causal link between the harm avoided and the illegal act. Green proffered no evidence of an ongoing, imminent danger after he left his residence—two hours had passed. Circuit precedent, especially Bell and Parker, bars a self-defense claim when the weapon remains under possession long after the immediate threat has ceased.

c. Sentencing Enhancements: Under § 2K2.1(b)(6)(B), the Government must prove by a preponderance that the defendant used or carried the firearm in connection with another felony. Attorney argument alone is not evidence. Nor may a court rely on PSR allegations to which the defendant lodges specific objection unless the Government meets its burden. The same rule applies to § 3C1.1 obstruction findings: reliable proof is required, and explicit factual findings must appear on the record. The Court of Appeals vacated two improperly supported enhancements and remanded for resentencing.

3. Impact

  • Reaffirms that a Terry stop may be based on cumulative, timely data (shots-fired reports, shell casings, dispatch logs) plus evasive conduct.
  • Strengthens the gatekeeping function for self-defense in felon-possession cases: only an immediate emergency justifies retaining the weapon.
  • Clarifies the Government’s burden at sentencing: factual enhancements must rest on admissible evidence meeting a preponderance standard, not attorney assertion;
  • Requires district courts to make explicit, supported findings when imposing enhancements under §§ 2K2.1 and 3C1.1;
  • Provides a roadmap for defense counsel to object vigorously to PSR assertions and demand proof.

Complex Concepts Simplified

  • Terry Stop: A brief police detention supported by reasonable suspicion—less than probable cause but more than a hunch.
  • Probable Cause vs. Reasonable Suspicion: Probable cause means a “substantial chance” a crime occurred; reasonable suspicion is a lower threshold based on specific, articulable facts.
  • Search Incident to Arrest: After a lawful arrest, officers may search the person and immediate surroundings for weapons or evidence.
  • Justification/Necessity Defense: An affirmative defense requiring proof of an unavoidable, imminent harm that the defendant acted to avert—no reckless placement into danger and no reasonable legal alternative.
  • Sentencing Enhancements: Adjustments under the U.S. Sentencing Guidelines that raise the offense level when the defendant’s conduct meets certain defined criteria, e.g., using a weapon in a separate felony or obstructing justice.
  • Preponderance of the Evidence: The standard at sentencing: “more likely than not” that a fact is true (a lower burden than “beyond a reasonable doubt”).

Conclusion

United States v. Green delivers three key lessons for federal practitioners:

  1. Front-end Fourth Amendment challenges to gun-possession arrests hinge on the totality of the circumstances—reports, observations, and suspect behavior all count;
  2. Self-defense is a narrowly confined exception in § 922(g)(1) prosecutions: absent an ongoing, imminent threat at the moment of gun seizure, the defense fails;
  3. At sentencing, the Government must produce reliable proof for each challenged enhancement, and district courts must make clear factual findings before raising the defendant’s Guidelines range.

By affirming the conviction, vacating two enhancements, and remanding for resentencing, the Eleventh Circuit has clarified both Fourth Amendment scope and sentencing protocols in felon-in-possession cases—strengthening procedural safeguards and delineating the narrow path for justification defenses.
