A defendant must possess advance knowledge that a confederate will use or carry a firearm to be convicted for aiding and abetting under § 924(c).
Professor Notes

In Rosemond v. United States, the Supreme Court ruled that for a defendant to be convicted of aiding and abetting under 18 U.S.C. § 924(c), the prosecution must demonstrate that the defendant had advance knowledge of a confederate's intentions to use or carry a firearm. This case emphasizes the importance of mens rea in criminal liability, particularly in the context of firearm usage in drug trafficking crimes. The Court's decision underscores the necessity of precise jury instructions that incorporate the requirement of advance knowledge, thereby portraying a clear demarcation between mere participation in a crime and the specific culpability associated with the use of firearms.

The ruling highlights the role of intent within aiding and abetting liability, reinforcing the critical concept that mere association with criminal activity or co-participation does not automatically equate to liability for further crimes executed by co-conspirators without the requisite knowledge of their intentions to employ dangerous weapons. Educators should emphasize the importance of understanding what constitutes adequate notice and the challenges in proving or disproving aids and abets culpability in complex criminal scenarios.
