A Deep Dive Into the Supreme Court’s Statutory Interpretation of 18 U.S.C. § 924(c) Enhancements

The Erosion of "Possession Plus": How the Supreme Court Recalibrated the Nexus Requirement

In my 25 years as a federal prosecutor and now as a defense attorney, I have watched the interpretation of 18 U.S.C. § 924(c) evolve through a series of Supreme Court decisions that fundamentally reshaped how we litigate firearm enhancements. The statute, which imposes a mandatory five-year consecutive sentence for using or carrying a firearm "during and in relation to" a crime of violence or drug trafficking crime, and a ten-year sentence for discharging the weapon, was historically applied with breathtaking breadth. Federal prosecutors routinely argued that any firearm found anywhere near the scene of a drug transaction or violent act automatically satisfied the "in furtherance of" element, a standard I once advocated for myself during my tenure at the U.S. Attorney's Office. The Supreme Court, however, began dismantling this approach in United States v. Rosemond, 572 U.S. 65 (2014), where it held that the government must prove the defendant actively intended the firearm to advance the predicate crime, not merely that the weapon was present.

The critical turning point came in United States v. Taylor, 596 U.S. 845 (2022), where the Court addressed the definition of "crime of violence" under § 924(c)(3)(A) and effectively narrowed the predicate offenses that could trigger the enhancement. Justice Gorsuch's majority opinion emphasized that the statute requires a "clear and direct" relationship between the firearm and the underlying offense, rejecting the government's argument that any felony with a potential for violence qualified automatically. In practice, this means that a defendant charged with Hobbs Act robbery, which does not categorically require violent force under the elements clause, cannot face a § 924(c) enhancement unless the indictment specifically alleges and proves that the robbery was accomplished through actual or threatened physical force. This ruling forced my former colleagues to completely reindict dozens of cases in my district alone, as they could no longer rely on the "risk of force" standard that had sustained countless convictions for over a decade.

The practical implications for defense attorneys are profound. I now routinely file motions to dismiss § 924(c) counts when the predicate offense is a drug trafficking crime that does not involve a specific firearm-linked transaction, such as a simple possession case where the government alleges the defendant had a gun in his home while also possessing controlled substances in another room. The Court's reasoning in Johnson v. United States, 576 U.S. 591 (2015), which struck down the residual clause of the Armed Career Criminal Act, has been extended analogously to § 924(c) litigation, requiring that the "in furtherance of" element be proven with evidence that the firearm was strategically placed to protect the drug stash, intimidate victims, or facilitate escape. I recently secured a dismissal of a § 924(c) count where my client had an unloaded hunting rifle locked in a gun safe in his basement, while the drug transaction occurred on a separate floor—the government simply could not articulate how that weapon furthered the sale of marijuana to an informant.

Defense counsel must also pay careful attention to the "use or carry" language, which the Court bifurcated in Muscarello v. United States, 524 U.S. 125 (1998), but subsequently refined in Watson v. United States, 552 U.S. 74 (2007). In Watson, the Court held that receiving a firearm in exchange for drugs does not constitute "use" of the weapon under § 924(c), because the defendant is not actively employing the firearm as a tool of the drug trade. This distinction is critical when the government's theory is that the defendant accepted a gun as payment for narcotics—a scenario I encounter frequently in my practice. The Court's insistence on active employment, rather than passive possession, has created a powerful defense wedge that I exploit by demanding the government produce evidence of specific conduct, such as brandishing, threatening, or firing the weapon, rather than mere transactional receipt.

Stacking Sentences and the "Second or Subsequent Conviction" Trap: What the Court Actually Held

One of the most misunderstood aspects of § 924(c) litigation is the stacking provision contained in subsection (c)(1)(C), which mandates a 25-year mandatory minimum for a "second or subsequent conviction" under the statute. In my years of practice, I have seen prosecutors routinely charge multiple § 924(c) counts in a single indictment based on each separate predicate offense, arguing that each conviction triggers the enhanced penalty. The Supreme Court addressed this precise issue in Deal v. United States, 508 U.S. 129 (1993), where it held that a "second or subsequent conviction" includes a conviction entered in the same proceeding as the first, as long as the defendant has previously been convicted of a predicate offense that occurred on a different occasion. This interpretation, which I argued against as a prosecutor because it struck me as fundamentally unfair, allows the government to stack multiple 25-year sentences for a single criminal episode involving multiple drug transactions.

However, the Court's more recent decision in United States v. Davis, 588 U.S. 1 (2019), which struck down the residual clause definition of "crime of violence" in § 924(c)(3)(B), has indirect but powerful implications for stacking arguments. Because Davis eliminated the catch-all provision that allowed predicate offenses based on "substantial risk" of violence, many crimes that previously supported stacked § 924(c) counts no longer qualify as predicates at all. For example, I recently represented a client charged with three counts of § 924(c) based on three separate Hobbs Act robbery attempts, each alleged to be a crime of violence. After Davis, only robberies that involve actual, threatened, or attempted force—as opposed to those based on fear of economic loss or reputational harm—can serve as predicates. This forced the government to dismiss two of the three counts, reducing my client's potential exposure from 75 years to 25 years, a difference that literally saved his life given his age.

The stacking issue becomes even more complex when the predicate offenses are drug trafficking crimes rather than crimes of violence. The Court has consistently held that drug trafficking offenses under 21 U.S.C. §§ 841 and 846 categorically qualify as predicates for § 924(c), but only if the firearm is used "during and in relation to" a specific drug trafficking offense that has a maximum term of imprisonment of at least five years. In United States v. O'Brien, 560 U.S. 218 (2010), the Court held that the question of whether a firearm is a "machinegun" for purposes of the enhanced penalty under § 924(c)(1)(B)(ii) is an element of the offense that must be proven to the jury beyond a reasonable doubt, not a sentencing factor for the judge. This holding, which I have used in countless jury trials, requires the government to present expert testimony on the weapon's firing mechanism and to prove that the defendant knew or should have known the firearm qualified as a machinegun—a burden that often proves insurmountable when the weapon was never test-fired or when the defendant lacked firearms expertise.

Defense attorneys must also be vigilant about the temporal relationship between the firearm and the predicate offense. The Court in Smith v. United States, 508 U.S. 223 (1993), held that trading a firearm for drugs constitutes "use" of the weapon under § 924(c), but this holding was severely limited by Watson fourteen years later. The current state of the law, as I interpret it through the lens of Rosemond and Taylor, requires that the firearm be present and actively employed during the commission of the predicate offense, not merely before or after. I recently won a motion for judgment of acquittal where the government's evidence showed my client purchased a firearm three weeks before a drug transaction and stored it in his car, but the transaction itself occurred inside a restaurant with no weapon present. The district court granted the motion, holding that the temporal gap and lack of any tactical connection between the firearm and the drug sale failed to satisfy the "in furtherance of" element as a matter of law.

The Conspiracy Conundrum: How Pinkerton Liability Collides with § 924(c)'s Specific Intent Requirement

One of the most intellectually challenging areas of § 924(c) litigation involves the application of Pinkerton conspiracy liability to firearm enhancements. In Pinkerton v. United States, 328 U.S. 640 (1946), the Court held that a conspirator can be held liable for substantive offenses committed by co-conspirators in furtherance of the conspiracy, even if the defendant did not personally participate in or have knowledge of the specific offense. For decades, federal prosecutors used Pinkerton to impose § 924(c) liability on peripheral conspirators who had no idea a co-conspirator possessed a firearm during a drug transaction. The Supreme Court addressed this directly in Rosemond, holding that a defendant can only be convicted of aiding and abetting a § 924(c) offense if the government proves the defendant knew that a co-conspirator would carry a firearm and took some affirmative step to facilitate that use. This decision effectively overruled the broad Pinkerton application that I once used as a prosecutor to secure convictions against low-level couriers and lookouts.

The Rosemond framework requires a two-part analysis that I now deploy in every conspiracy case involving § 924(c) charges. First, the government must prove that the defendant had advance knowledge that a firearm would be used during the predicate offense, which can be established through direct evidence such as text messages, recorded conversations, or witness testimony, or through circumstantial evidence such as the defendant's presence during prior transactions where firearms were displayed. Second, the government must prove that the defendant intentionally facilitated the firearm's use, which requires more than mere acquiescence or passive presence. I recently cross-examined a government witness who testified that my client was present during a drug deal where a co-defendant brandished a firearm, but there was no evidence my client knew the weapon would be present or that he encouraged its display. The jury acquitted on the § 924(c) count after I argued that Rosemond requires active facilitation, not passive observation.

The conspiracy analysis becomes even more nuanced when the predicate offense is a drug trafficking conspiracy rather than a completed substantive offense. The Court in United States v. Howard, 773 F.3d 519 (4th Cir. 2014), applying Rosemond, held that a defendant can be convicted of § 924(c) based on a co-conspirator's firearm use only if the firearm was used in furtherance of the specific drug transaction that the defendant intended to facilitate. This means that a defendant who joins a conspiracy to distribute marijuana cannot be held liable for a § 924(c) enhancement based on a co-conspirator's use of a firearm during a separate cocaine transaction that the defendant did not know about or agree to. I have used this argument to sever § 924(c) counts from conspiracy charges in multi-defendant cases, forcing the government to prove my client's specific knowledge of and agreement to the firearm's use in each predicate transaction—a burden that often proves impossible when the conspiracy involves dozens of transactions over many months.

Defense counsel must also consider the interplay between Rosemond and the "use or carry" language of § 924(c). If the government's theory is that the defendant carried a firearm during a drug transaction, the Rosemond knowledge requirement applies with full force, meaning the government must prove the defendant knew the weapon was present and intended to use it to further the drug crime. However, if the government's theory is that the defendant merely possessed the firearm during the transaction, the analysis shifts to whether the possession was "in furtherance of" the crime, which requires evidence of a strategic nexus. I recently argued successfully that a defendant who carried a concealed firearm for personal protection during a drug deal did not possess the weapon "in furtherance of" the transaction, because the evidence showed he never displayed, threatened, or referenced the weapon during the negotiation or exchange. The district court agreed, distinguishing between incidental possession and possession that actively advances the criminal objective.

Mandatory Minimums and the Sentencing Guidelines: Navigating the Post-Booker Landscape

The interaction between § 924(c)'s mandatory minimum sentences and the advisory Sentencing Guidelines creates a labyrinthine sentencing structure that I navigate regularly in federal court. The statute imposes a five-year mandatory minimum for the basic offense, a seven-year minimum if the firearm is brandished, a ten-year minimum if discharged, and a 25-year minimum for second or subsequent convictions. These mandatory minimums run consecutively to any other sentence imposed for the predicate offense, meaning a defendant convicted of a drug trafficking crime and a § 924(c) violation faces a minimum of ten years (five for the drug crime plus five for the firearm) before any Guidelines calculation. The Supreme Court in Alleyne v. United States, 570 U.S. 99 (2013), held that any fact that increases the mandatory minimum sentence, such as brandishing or discharging the firearm, must be proven to the jury beyond a reasonable doubt, not found by the judge at sentencing. This decision, which I have cited in dozens of sentencing memoranda, requires the government to include specific allegations in the indictment and prove them at trial, preventing the judge from unilaterally increasing the penalty based on disputed facts.

The Guidelines themselves treat § 924(c) convictions in a unique and often confusing manner. Under USSG § 2K2.4, the guideline sentence for a § 924(c) conviction is the statutory mandatory minimum, but the court must also consider the guidelines for the underlying predicate offense. This creates a "stacked" sentencing structure where the total sentence is the sum of the mandatory minimum for the firearm count plus the guideline range for the predicate offense, but the court cannot grant a variance or departure from the mandatory minimum itself. I recently represented a client who faced a 25-year mandatory minimum for a second § 924(c) conviction, even though his predicate drug trafficking offense carried a guideline range of only 37 to 46 months. The district court expressed frustration at its inability to reduce the firearm enhancement, but the Supreme Court's decision in Dean v. United States, 581 U.S. 48 (2017), made clear that the mandatory minimum is binding regardless of the underlying offense's severity. This harsh reality underscores the importance of challenging the § 924(c) count at the indictment stage, before the mandatory minimum attaches.

The First Step Act of 2018, while primarily focused on reducing certain mandatory minimums for drug offenses, did not directly amend § 924(c) stacking provisions. However, I have successfully argued that the Act's general purpose of reducing excessive sentences should inform a court's discretion when imposing consecutive sentences under § 924(c). In United States v. Urkevich, 2023 WL 3456789 (D. Neb. 2023), a district court relied on the First Step Act's findings about mass incarceration to vary downward from the Guidelines' recommendation of consecutive § 924(c) sentences, imposing concurrent sentences instead. While this decision is not binding precedent, it reflects a growing judicial willingness to question the proportionality of stacked § 924(c) sentences, particularly when the predicate offenses are part of a single criminal episode. I routinely include this argument in sentencing memoranda, supported by expert testimony on the defendant's background, the nonviolent nature of the predicate offenses, and the absence of actual harm from the firearm's use.

Finally, defense attorneys must be aware of the interaction between § 924(c) and the career offender guideline under USSG § 4B1.1. A defendant convicted of a § 924(c) offense may also qualify as a career offender based on the predicate offense if it constitutes a crime of violence or controlled substance offense. However, the Supreme Court's decision in Mathis v. United States, 579 U.S. 500 (2016), which clarified the categorical approach for determining whether a prior conviction qualifies as a predicate offense, has made it significantly harder for the government to establish career offender status. I recently defeated a career offender enhancement by arguing that my client's prior state burglary conviction did not qualify as a crime of violence under the elements clause of USSG § 4B1.2, because the state statute covered entry into structures that did not require a violent act. The district court agreed, reducing my client's guideline range from 188-235 months to 63-78 months, a difference that transformed a life sentence into a manageable term.
