572 U.S. 65, 134 S. Ct. 1240, 188 L. Ed. 2d 248 (2014)
Justus Rosemond participated in a drug transaction arranged by Vashti Perez to sell a pound of marijuana to Ricardo Gonzales and Coby Painter.1 Perez drove to a local park accompanied by Ronald Joseph and Rosemond to complete the exchange.2 Upon arrival, Gonzales entered the backseat of the vehicle to inspect the marijuana while Painter remained outside.3 Instead of paying, Gonzales punched the backseat passenger and fled with the drugs.4 As Gonzales and Painter ran away, one of the male passengers exited the car and fired several shots from a semiautomatic handgun before the three individuals pursued the buyers in their vehicle.5
A police officer responding to a dispatcher's alert pulled over the car before the pursuers could catch Gonzales and Painter.6 The Government subsequently charged Rosemond with violating 18 U.S.C. §924(c) by using a gun in connection with a drug trafficking crime or, alternatively, aiding and abetting that offense under 18 U.S.C. §2.7 Because the identity of the shooter remained disputed, the prosecution pursued both theories at trial: that Rosemond himself fired the weapon or that he aided and abetted Joseph's use of the firearm.8
At trial, the District Judge instructed the jury on aiding and abetting principles. A person aids or abets if he willfully and knowingly associates himself with the crime and seeks by some act to help make it succeed.9 The judge further instructed that Rosemond could be convicted of aiding and abetting the §924(c) offense if he knew his cohort used a firearm in the drug trafficking crime and knowingly and actively participated in the drug trafficking crime.10 Rosemond had proposed an alternative instruction requiring that he intentionally took action to facilitate or encourage the use of the firearm specifically.11
The jury convicted Rosemond of the §924(c) violation along with other offenses, resulting in a consecutive 120-month sentence for that count.12 The Tenth Circuit affirmed the conviction, upholding the District Court's aiding and abetting instructions against Rosemond's challenge.13 The Supreme Court granted certiorari to address the requirements for aiding and abetting liability under these circumstances.14
Whether the affirmative act requirement for aiding and abetting a §924(c) offense can be satisfied by active participation in the underlying drug trafficking crime alone?15
Yes. Rosemond actively participated in the drug transaction arranged by Vashti Perez by accompanying her and Ronald Joseph to the park for the marijuana sale to Ricardo Gonzales and Coby Painter.18 The commission of the drug trafficking crime constitutes an essential conduct element of the §924(c) offense under the statute's combination of predicate crime and firearm use.19 By facilitating the drug element through his presence and involvement in the exchange attempt, Rosemond necessarily assisted completion of the whole §924(c) violation.20
The common-law principle that aiding any part of a criminal venture satisfies the conduct requirement continues to govern §2, rendering participation in the drug component alone sufficient.21
Active participation in the underlying drug trafficking crime alone satisfies the affirmative act requirement for aiding and abetting a §924(c) offense.22
Whether the intent requirement for aiding and abetting a §924(c) offense requires advance knowledge that a confederate would use or carry a firearm?23
Aiding and abetting requires intent extending to the whole crime.24 This is satisfied when the defendant actively participates in the criminal venture with advance knowledge that a confederate would use or carry a gun.25 That knowledge must come at a time when the accomplice has a reasonable opportunity to walk away from the enterprise.26
Yes. Rosemond took part in the drug deal at the park where one confederate fired shots after the robbery attempt by Gonzales and Painter.27 The intent standard demands that the defendant know of the firearm in advance so he can choose to alter the plan or withdraw rather than proceed with an armed offense.28 Knowledge acquired only when the gun appears at the scene fails to show the requisite intent because the accomplice may already have completed his assistance or lack any realistic chance to exit the crime.29
The jury instructions permitted conviction based on mere knowledge that a cohort used a firearm without addressing the timing of that knowledge.30
The intent requirement for aiding and abetting a §924(c) offense requires advance knowledge that a confederate would use or carry a firearm.31

Justice Alito concurs in the first twelve pages of the majority opinion addressing the affirmative act and basic intent standards but dissents from the requirement of a realistic opportunity to walk away.32 He argues that this converts the traditional affirmative defense of necessity or duress into part of the mens rea element and improperly shifts a difficult burden to the prosecution to disprove facts peculiarly within the defendant's knowledge.33 Alito maintains that purposeful intent under Nye & Nissen remains compatible with motives arising from duress or necessity and that the majority's approach represents an unprecedented alteration of aiding and abetting law.34
Whether the trial court's jury instructions on aiding and abetting were erroneous for failing to require that the defendant knew in advance that one of his cohorts would be armed?35
Yes. The District Court instructed the jury that Rosemond aided and abetted if he knew his cohort used a firearm in the drug trafficking crime and knowingly and actively participated in that crime.38 This formulation omitted any direction to determine when Rosemond acquired the knowledge, allowing conviction even if he learned of the gun only when it was fired during the chase after Gonzales and Painter fled with the marijuana.39 The prosecutor's closing argument reinforced the error by asserting that presence at a drug deal when shots are fired necessarily implies knowledge of the gun.40
The Supreme Court therefore held the instructions erroneous and remanded for consideration of preservation and harmlessness.41
The trial court's jury instructions on aiding and abetting were erroneous for failing to require that the defendant knew in advance that one of his cohorts would be armed.42
