Whether other subdivisions of 18 U.S.C. § 922(g) require knowledge of collateral law

question presented is whether other subdivisions of 18 U.S.C. § 922(g) require knowledge of collateral law. 2. In Greer v. United States, 141 S.Ct. 2090 (2021), this Court stated that a defendant may satisfy his burden of demonstrating plain error in an omittedelement case by making an argument or representation on appeal regarding the omitted element. Petitioner in this case requested an opportunity to make such a showing, but his request was ignored by the Ninth Circuit panel, which relied solely on trial evidence in analyzing plain error. The second question presented is whether appellate courts must give a defendant an opportunity to make an evidentiary proffer to satisfy his burden of demonstrating plain error. ii STATEMENT OF RELATED CASES e United States v.
