Section 848(e)(1)(B) Requires Intentional Conduct and Categorically Qualifies as a Crime of Violence

1. Introduction

In United States v. Barrett, the Tenth Circuit held that causing the intentional killing of a law enforcement officer under 21 U.S.C. § 848(e)(1)(B) requires an intentional mental state, not merely recklessness. Consequently, the offense categorically qualifies as a “crime of violence” under the elements clause of 18 U.S.C. § 924(c)(3)(A).

The case arose from the 1999 execution of a no-knock search warrant at Kenneth Eugene Barrett’s Oklahoma residence during a methamphetamine investigation. Barrett fired at the officers, killing Trooper David Eales and wounding Trooper John Hamilton. Following state proceedings, federal prosecutors obtained convictions for two firearm offenses involving a resulting death and for intentionally killing a state law enforcement officer in connection with a drug offense.

This appeal concerned only the firearm conviction in Count 2, whose predicate crime of violence was the § 848(e)(1)(B) homicide charged in Count 3. Barrett argued that the homicide statute could reach someone who recklessly caused another person to kill intentionally. If so, the statute would encompass conduct falling outside the elements clause, undermining the associated firearm conviction after the Supreme Court invalidated § 924(c)’s alternative residual clause.

The court rejected that interpretation. Its central contribution is a contextual reading of the word “causes”: although causation does not invariably imply intent, its placement among intentional-action verbs, alongside express references to intentional killing and exceptionally severe penalties, requires intentional conduct here.

2. Procedural Background and Summary of the Decision

The convictions and earlier collateral proceedings

Barrett’s first state trial ended with a hung jury. At a second trial, he was acquitted of first-degree murder and other charges but convicted of first-degree manslaughter and assault and battery with a dangerous weapon. He received a combined thirty-year sentence.

A subsequent federal prosecution produced three convictions:

1. Count 1: a firearm offense connected to drug-trafficking crimes, resulting in death, under 18 U.S.C. § 924(c)(1)(A) and (j).
2. Count 2: a firearm offense connected to a crime of violence, under the same provisions.
3. Count 3: intentionally killing a state law enforcement officer during a drug-trafficking crime, under 21 U.S.C. § 848(e)(1)(B), which supplied Count 2’s predicate offense.

The federal court imposed life sentences on Counts 1 and 2 and a death sentence on Count 3. Although the convictions and death sentence initially survived direct appeal, later ineffective-assistance litigation resulted in vacatur of the death sentence and a remand for resentencing on Count 3. The government subsequently withdrew its notice of intent to seek death.

The successive § 2255 challenge

Separately, Barrett obtained authorization to file a second or successive motion under 28 U.S.C. § 2255 following United States v. Davis, 588 U.S. 445 (2019). He sought to vacate Count 2 and obtain additional sentencing relief on Counts 1 and 3. The district court denied relief, concluding that the homicide predicate satisfied the surviving elements clause. It also treated the requested relief concerning Counts 1 and 3 as outside the authorization for the successive motion.

After Barrett moved under Federal Rule of Civil Procedure 59(e), the district court maintained its merits ruling but issued a limited certificate of appealability permitting a challenge to Count 2. The certificate excluded his contentions that invalidating Count 2 would also require relief on Counts 1 and 3.

The appellate disposition

The Tenth Circuit affirmed the denial of both the § 2255 motion and the related motion to alter or amend the judgment. Its reasoning followed three steps:

1. It assumed without deciding that Count 2 had rested on the unconstitutional residual clause.
2. It held that § 848(e)(1)(B) independently qualifies under the elements clause because every specified inculpatory action requires an intentional mental state.
3. It therefore concluded that any assumed residual-clause error was harmless.

The court did not find as a historical fact that Barrett’s original conviction actually depended on the residual clause. Its affirmance rested on the availability of a valid elements-clause basis under current law.

3. Analysis: The Governing Statutory Framework

The two statutes

Section 924(c) imposes additional punishment for specified firearm conduct connected to a qualifying predicate offense. Following United States v. Davis, a predicate asserted to be a crime of violence must satisfy § 924(c)(3)(A), which requires a felony having:

“as an element the use, attempted use, or threatened use of physical force against the person or property of another.”

The disputed predicate, § 848(e)(1)(B), applies in specified connections with a felony federal drug violation to a person who:

“intentionally kills or counsels, commands, induces, procures, or causes the intentional killing” of a qualifying law enforcement officer, where “such killing results.”

The statute authorizes a prison term of at least twenty years, up to life imprisonment, or death.

Why the defendant’s own mental state mattered

Barrett’s argument distinguished the killer’s intent from the intent of someone who caused the killing. An intentional killing by one person does not, as a matter of ordinary logic, necessarily establish that everyone contributing to it intended the death. Barrett maintained that the statute’s unmodified word “causes” preserved that distinction and permitted liability for reckless causation.

The court therefore had to determine whether the statute required intentional conduct by the person being prosecuted—not simply an intentional act by the ultimate killer. That question was decisive because the categorical approach examines the offense’s legal requirements rather than Barrett’s actual shooting conduct.

4. Analysis: Precedents Cited and Their Influence

A. The constitutional decisions opening the collateral-review pathway

Johnson v. United States, 576 U.S. 591 (2015)

Johnson v. United States invalidated the Armed Career Criminal Act’s residual clause and provided the initial foundation for Barrett’s application to pursue successive collateral relief. Its importance here was primarily procedural and doctrinal background: it began the line of vagueness decisions eventually reaching § 924(c).

Welch v. United States, 578 U.S. 120 (2016)

Welch v. United States made the rule announced in Johnson v. United States retroactively applicable on collateral review. Barrett invoked these decisions together in seeking authorization for his successive motion.

Sessions v. Dimaya, 584 U.S. 148 (2018)

Sessions v. Dimaya, concerning another residual definition of a crime of violence, formed an intermediate step in the constitutional development. Barrett supplemented his pending application to rely on it, but it was not the ultimate basis for deciding whether his predicate offense survived.

United States v. Davis, 588 U.S. 445 (2019)

United States v. Davis directly controlled the validity of § 924(c)(3)(B), holding its residual clause unconstitutionally vague. It removed that clause as a lawful basis for Count 2 and made the elements-clause inquiry necessary. It did not, however, automatically invalidate convictions supported by predicates independently satisfying the elements clause.

In re Mullins, 942 F.3d 975 (10th Cir. 2019)

In re Mullins established within the circuit that United States v. Davis announced a new constitutional rule made retroactively applicable to cases on collateral review. That conclusion supported authorization of Barrett’s successive motion under § 2255(h). The authorization order identified as In re Barrett supplied the case-specific permission to proceed; it did not resolve the merits.

B. The categorical approach and the exclusion of recklessness

United States v. Taylor, 596 U.S. 845 (2022)

United States v. Taylor supplied the governing categorical methodology. The question is whether the predicate felony always requires proof of the necessary force element, not whether the particular defendant committed it violently. Accordingly, Barrett’s actual rifle fire could not substitute for a determination of the minimum mental state required by § 848(e)(1)(B).

Borden v. United States, 593 U.S. 420 (2021)

Borden v. United States furnished the substantive dividing line. Its four-Justice plurality concluded that reckless offenses do not satisfy the Armed Career Criminal Act’s elements clause. Justice Thomas agreed that recklessness was insufficient but relied on “use of physical force,” rather than the plurality’s emphasis on force “against the person of another.”

The Tenth Circuit applied that exclusion of recklessness to the relevant language of § 924(c). Thus, if Barrett’s proposed reckless-causation interpretation were correct, it would defeat categorical qualification. The decision carefully acknowledged the differing rationales supporting the result in Borden v. United States.

United States v. Melgar-Cabrera, 892 F.3d 1053 (10th Cir. 2018)

This precedent established de novo review of statutory interpretation and the legal classification of an offense as a crime of violence. It supported the appellate court’s independent examination of § 848(e)(1)(B).

C. The closest substantive analogue

United States v. Smith, 104 F.4th 314 (D.C. Cir. 2024), was the most directly influential persuasive authority. It considered the identical operative language in § 848(e)(1)(A), the neighboring subsection. The Tenth Circuit adopted its central interpretive insights:

• Expressly supplied intent language ordinarily governs the relevant culpable acts unless context indicates otherwise.
• The verbs surrounding “causes” themselves describe intentional action.
• The statute’s severe penalties weigh against interpreting it to cover recklessness.

That decision also explained that “intentional” encompasses at least purposeful conduct and may cover both purposeful and knowing conduct. Barrett’s parties did not dispute that understanding. The Tenth Circuit’s holding therefore establishes an intentional threshold above recklessness without resolving every possible distinction between purpose and knowledge.

D. Mens rea presumptions and contextual interpretation

• United States v. Serawop, 410 F.3d 656 (10th Cir. 2005), and Staples v. United States, 511 U.S. 600 (1994), established that identifying a statute’s required mental state is a question of statutory construction informed by the common-law background of criminal culpability.
• Morissette v. United States, 342 U.S. 246 (1952), supplied the traditional emphasis on punishing a “vicious will,” quoted through Ruan v. United States, 597 U.S. 450 (2022). These authorities supported reading the statute against a presumption of culpable mental-state requirements.
• Ruan v. United States also supported a more specific inference: severe penalties counsel in favor of a strong scienter requirement. This principle reinforced the court’s textual analysis rather than independently supplying the entire rule.
• Liparota v. United States, 471 U.S. 419 (1985), and Rehaif v. United States, 588 U.S. 225 (2019), supported extending an expressly stated culpability requirement across material elements absent a contrary statutory purpose. The opinion quoted Rehaif v. United States’s reliance on Model Penal Code § 2.02(4).
• Fischer v. United States, 603 U.S. 480 (2024), supplied the contextual canon noscitur a sociis. Through its quotations of United States v. Williams, 553 U.S. 285 (2008), and Gustafson v. Alloyd Co., 513 U.S. 561 (1995), it explained why an ambiguous word should not receive a breadth inconsistent with neighboring words.
• Abramski v. United States, 573 U.S. 169 (2014), reinforced the same method: statutory words must be read in context, not in isolation.

Together, these cases allowed the court to reject a dictionary-based reading under which “causes” could encompass any causal contribution, regardless of the defendant’s intention. Importantly, the general presumption of mens rea alone does not establish that every crime requires intent rather than recklessness; the court relied on that presumption together with this statute’s particular language and structure.

E. Harmless error and the use of current law

• United States v. Driscoll, 892 F.3d 1127 (10th Cir. 2018), supplied the two-stage inquiry: identify error, then determine whether it caused the requisite prejudice.
• Brecht v. Abrahamson, 507 U.S. 619 (1993), supplied the “substantial and injurious effect or influence” formulation used in that inquiry.
• United States v. Lewis, 904 F.3d 867 (10th Cir. 2018), directed the court to apply current law at the harmless-error stage because that stage concerns the availability of a remedy.
• United States v. Bowen, 936 F.3d 1091 (10th Cir. 2019), supported both the availability of collateral challenges following United States v. Davis and strictly de novo review where the district court denied relief as a matter of law on an uncontested trial record.

These authorities permitted the court to bypass the disputed historical question of which clause originally supported Count 2. Even accepting Barrett’s premise of residual-clause error, the conviction survived because its predicate satisfies the elements clause today.

F. Earlier Barrett decisions and other procedural authorities

The two decisions titled United States v. Smith served different purposes: the 2024 D.C. Circuit case materially supported statutory interpretation, while the 2014 Tenth Circuit case appeared in Barrett’s argument for broader sentencing relief.

5. Analysis: The Court’s Legal Reasoning

A. Intentionality permeates the statutory language

The court first emphasized that Congress did not leave § 848(e)(1)(B) silent about mental state. The provision expressly addresses a person who “intentionally kills” and one who brings about “the intentional killing.” Its concluding requirement that “such killing results” refers back to that intentional killing.

Reading those phrases together, the court found no textual basis for inserting a lower culpability standard into one of the listed ways of committing the offense. Instead, it applied the expressed intentional mental state to each inculpatory action: killing, counseling, commanding, inducing, procuring, and causing.

This was a contextual construction, not merely a claim that the adverb “intentionally” mechanically modifies every later verb. The court considered the repeated intent language and the overall arrangement of the provision.

B. “Causes” takes meaning from its neighboring verbs

The parties agreed that “counsels,” “commands,” “induces,” and “procures” imply intentional conduct. The court examined dictionary definitions describing recommendation, authoritative direction, persuasion, and deliberate effort.

“Causes” can have a broader meaning when isolated; careless driving, for example, can cause an accident. But the court rejected isolation as the proper interpretive method. Under noscitur a sociis, the surrounding deliberate-action verbs narrowed “causes” to intentional causation.

This reasoning is particularly important for non-shooters. The decision does not merely require that someone intentionally kill the officer. It requires intentional conduct by the defendant charged with bringing about that killing.

C. The penalty structure confirms the stronger mental-state requirement

Congress imposed the same severe sentencing range on direct killers and defendants who cause an intentional killing: at least twenty years, potentially life imprisonment or death. The court treated that equivalence as additional evidence against sweeping reckless causation into the statute.

Barrett offered the example of a drug-enterprise leader who sees officers approaching and tells subordinates to “do something.” A subordinate might interpret the instruction as a direction to kill even if the leader intended only the destruction of evidence. The court concluded that the prosecution would have to prove that the leader actually intended the killing through the instruction.

The example illustrates the evidentiary consequence of the holding. Ambiguous words followed by a killing do not alone eliminate the need to establish the defendant’s required mental state. The opinion did not require an express verbal command to kill; it required proof of intent.

D. The comparison with 18 U.S.C. § 2 did not justify a different reading

Barrett’s strongest structural argument compared § 848(e)(1)(B) with the federal accomplice-liability statute. Section 2(a) uses “counsels, commands, induces or procures,” while § 2(b) expressly refers to someone who “willfully causes” an act. Because § 848(e)(1)(B) uses “causes” without “willfully,” Barrett argued that Congress deliberately omitted a mental-state limitation.

The court explained why the two settings differ. In § 2(b), “causes” lacks the surrounding verbs and express intent language present in § 848(e)(1)(B). The modifier “willfully” makes the mental-state requirement clear there. In the homicide provision, Congress accomplished that clarification through context.

The decision therefore declines to treat every difference in wording between related statutes as controlling. A missing modifier does not establish a lower mental state when the provision’s own language supplies the necessary limitation.

E. The valid predicate made the assumed constitutional error harmless

Having rejected reckless causation, the court concluded that § 848(e)(1)(B) categorically satisfies the elements clause. The appellate dispute centered on mens rea; the opinion did not develop a separate, extensive analysis of every possible mechanism by which an intentional killing might occur.

Because the predicate remained valid, assumed reliance on the residual clause had not produced the substantial and injurious effect necessary for collateral relief. The associated Count 2 conviction therefore remained intact.

6. Potential Impact and Limits

Preserving a defined class of § 924(c) predicates

As a published Tenth Circuit decision, the opinion establishes that § 848(e)(1)(B) is an eligible crime-of-violence predicate under the elements clause. Future challenges based solely on the claim that its “causes” language permits reckless causation face a controlling answer within the circuit.

Requiring intent from defendants who bring about a killing

The ruling has a dual effect. It preserves associated firearm convictions, but it also confirms a meaningful culpability requirement for the underlying homicide offense. Prosecutors cannot rely merely on a defendant’s reckless contribution to someone else’s intentional killing.

Limiting the remedial reach of residual-clause invalidation

The decision illustrates why authorization to bring a successive motion does not establish entitlement to relief. A defendant may obtain review under United States v. Davis yet lose because the predicate independently satisfies the surviving elements clause. Courts may resolve such cases through harmless-error analysis without deciding historical reliance on the residual clause.

Reinforcing contextual mens rea interpretation

The opinion aligns the Tenth Circuit’s treatment of § 848(e)(1)(B) with the D.C. Circuit’s treatment of identical language in § 848(e)(1)(A). More broadly, it demonstrates that an apparently unmodified verb can carry a demanding mental-state requirement when neighboring terms, repeated culpability language, and penalties point in that direction.

Important boundaries

• The court did not hold that every homicide offense qualifies as a crime of violence.
• Its direct holding concerns § 848(e)(1)(B), not every provision using the word “causes.”
• It did not resolve every distinction between purposeful and knowing conduct.
• It did not separately decide the mental state applicable to every circumstance element, such as the officer’s official status.
• It did not decide the merits of Barrett’s proposed resentencing consequences for Counts 1 and 3.
• Its penalty-based reasoning was interpretive; it was not a separate constitutional ruling about capital eligibility.

7. Complex Concepts Simplified

Categorical approach

Examine what the law requires for conviction, not what this defendant actually did. A violent factual episode cannot cure a predicate statute that legally reaches disqualifying conduct.

Elements clause and residual clause

The elements clause asks whether the offense requires specified force. The former residual clause focused on the risk of force associated with an offense’s nature. The Supreme Court invalidated the latter as too vague.

Mens rea and scienter

These terms concern the defendant’s required mental state. Purpose, knowledge, recklessness, and negligence represent different levels of culpability. This case places the disputed conduct above recklessness.

Noscitur a sociis

A word is understood by the company it keeps. Here, “causes” was read alongside verbs describing deliberate action.

Harmless error

A legal error does not necessarily justify overturning a judgment. Here, even an assumed reliance on the invalid residual clause did not warrant relief because the predicate qualified under the valid elements clause.

Second or successive § 2255 motion

A later federal post-conviction motion subject to restrictive appellate authorization requirements. Permission to file opens the door to review; it does not decide whether the claim succeeds.

Certificate of appealability

The required permission to appeal specified issues in this collateral proceeding. Barrett’s certificate permitted the Count 2 challenge but excluded his broader claims concerning Counts 1 and 3.

De novo review

The appellate court decides the legal question independently, without deferring to the district court’s answer.

8. Conclusion

United States v. Barrett establishes that every listed culpable means of violating § 848(e)(1)(B), including causing another person’s intentional killing of a law enforcement officer, requires intentional conduct. The offense therefore categorically qualifies as a crime of violence under § 924(c)(3)(A).

The decision both preserves the associated firearm conviction and rejects liability under this homicide provision based merely on reckless causation. Its broader significance lies in combining contextual statutory interpretation with current-law harmless-error review: invalidation of a residual clause does not require relief when the predicate independently satisfies the surviving elements clause.
