Whether a defendant charged with aiding and abetting a § 924(c) firearm offense must take an affirmative act specifically directed at facilitating the firearm's use or carriage.
Holding
No. A defendant's active participation in the predicate drug-trafficking or violent crime satisfies the affirmative-act requirement, even if the defendant did nothing specifically to facilitate the firearm element.
Reasoning
Aiding-and-abetting liability under § 2 requires both an affirmative act that furthers the offense and an intent to facilitate its commission. Under common-law principles incorporated into § 2, a participant need not assist every element of a crime; aiding any component of a unified criminal venture can constitute aiding the whole offense.
Section 924(c) is a combination crime: it punishes the conjunction of a predicate drug-trafficking or violent crime and the use or carriage of a firearm. The predicate offense is therefore an essential conduct element of § 924(c), not a legally insignificant backdrop to the gun offense.
Accordingly, a defendant who helps carry out the drug transaction has helped bring about one component of the complete § 924(c) offense. The law does not require proof that the defendant also obtained, carried, fired, or otherwise assisted with the gun.
