Facts
- Justus C. Rosemond joined two accomplices in a marijuana sale in a Utah park.
- During the transaction, a buyer grabbed the marijuana and ran without paying.
- Someone in Rosemond’s group fired shots at the fleeing buyer; the evidence did not clearly identify the shooter.
- The government charged Rosemond with violating 18 U.S.C. § 924(c) (use or carrying of a firearm during a drug-trafficking crime), including under an aiding-and-abetting theory via 18 U.S.C. § 2.
- The trial court instructed the jury that aiding and abetting required (1) knowledge that a cohort used a firearm in the drug-trafficking crime and (2) knowing, active participation in the drug-trafficking crime, without requiring advance knowledge of the gun or intent as to the firearm element.
- The jury convicted Rosemond on the § 924(c) count, and the Tenth Circuit affirmed.
Issues
- What mens rea is required to convict a defendant of aiding and abetting a § 924(c) offense under 18 U.S.C. § 2.
- Whether a defendant must have advance knowledge that a confederate will use or carry a firearm, or whether participation in the predicate crime plus knowledge of firearm use at some point is sufficient.
- Whether the jury instructions misstated the law by omitting any requirement of advance knowledge of the firearm.
Decision
- The Supreme Court vacated the judgment and remanded.
- To prove aiding and abetting a § 924(c) violation, the government must show the defendant actively participated in the predicate drug-trafficking (or violent) crime with advance knowledge that a confederate would use or carry a gun during the crime.
- “Advance knowledge” means knowledge acquired in time for the defendant to have a realistic opportunity to withdraw from the crime.
- The trial instructions were erroneous because they allowed conviction without requiring a finding that Rosemond knew ahead of time (or soon enough to withdraw) that a gun would be used or carried.
- The case was remanded for determination whether the instructional error was harmless.
Legal Principles
- Federal aiding-and-abetting liability under 18 U.S.C. § 2 requires (1) an affirmative act in furtherance of the offense and (2) intent to facilitate the offense’s commission.
- For the act requirement, an accomplice may satisfy § 2 by facilitating any element of the charged offense; with § 924(c), facilitating the predicate drug-trafficking crime can suffice.
- For the intent requirement in § 924(c) cases, the accomplice must intend the commission of the full “armed” crime, which requires advance knowledge that a confederate will use or carry a firearm.
- Knowledge of the firearm obtained only at a point when the defendant lacks a realistic opportunity to quit the criminal venture is generally insufficient to establish intent to aid and abet the § 924(c) offense.
Conclusion
The Court held that aiding and abetting a § 924(c) offense requires active participation in the predicate crime combined with advance knowledge that a confederate will use or carry a gun, so continued participation reflects intent to facilitate an armed offense; because the jury was not instructed to find such advance knowledge, the conviction was vacated and remanded for harmless-error review.
