scope of the statute, explaining that “the [original] section was directed at persons who chose to carry a firearm as an offensive weapon for a specific criminal act.” Id. Moreover, where the legislative history discusses changes in the coverage of the statute effected by the amendment, it does so expressly. Id. at 313 n. 9 (establishing as the predicate offense any “crime of violence” instead of any “felony”; expressly recognizing that this change both expands and restricts the scope of the statute); id. at 314 n. 10 (noting the broader coverage of the statute because of the elimination of the “unlawfully” requirement).
Although the legislative history surrounding the addition of the “in relation to” language is not entirely free of ambiguity, we interpret it as revealing an understanding on the part of the amending Congress that the earlier Congress intended to require a relation between the firearm and the underlying crime. See Russell v. Law Enforcement Assistance Administration, 637 F.2d 1255, 1258 n. 5 (9th Cir.1980) (using revised Law Enforcement Assistance Administration Act to resolve ambiguities in old act where “the revised language simply clarifies the original legislative intent”). While a later Congress’ understanding of the legislative intent of an earlier Congress is not binding on the courts, it is entitled to deference. Russ v. Wilkins, 624 F.2d 914, 924-25 (9th Cir.1980), cert. denied, 451 U.S. 908, 101 S.Ct. 1976, 68 L.Ed.2d 296 (1981); Chugach Natives, Inc. v. Doyon, Ltd., 588 F.2d 723, 730-31 (9th Cir.1979). See generally N. Singer, 2A Sutherland Statutory Construction § 49.11, at 414-15 (rev. 4th ed. 1984). We accord such deference here.
Although the legislative history of the original version of section 924(c) is sparse,
Simpson v. United States, 435 U.S. 6, 15, 98 S.Ct. 909, 914, 55 L.Ed.2d 70 (1978), the evident purpose of the statute was to impose more severe sanctions where firearms facilitated, or had the potential of facilitating, the commission of a felony.
See United States v. LaGuardia, 774 F.2d at 321;
United States v. Mason, 658 F.2d 1263, 1270-71 (9th Cir.1981). That purpose necessarily implies some relation or connection between the underlying criminal act and the use or possession of the firearm.
See United States v. Robertson, 706 F.2d 253, 256 (8th Cir.1983). Indeed, in a previous case arising under the statute, we suggested that “Congress did not intend to penalize one who happens to have a gun in his possession when he commits an entirely unrelated offense.”
United States v. Moore, 580 F.2d 360, 362 (9th Cir.),
cert. denied, 439 U.S. 970, 99 S.Ct. 463, 58 L.Ed.2d 430 (1978).
We interpret the statute that applied to Stewart as if it contained the requirement that the firearm be possessed “during and in relation to” the underlying offense. If the firearm is within the possession or control of a person who commits an underlying crime as defined by the statute, and the circumstances of the case show that the firearm facilitated or had a role in the crime, such as emboldening an actor who had the opportunity or ability to display or discharge the weapon to protect himself or intimidate others, whether or not such display or discharge in fact occurred, then there is a violation of the statute. See United States v. LaGuardia, 774 F.2d at 321; United States v. Mason, 658 F.2d at 1270-71.
Stewart did not request specific jury instructions regarding the relational element of the crime, but that does not preclude his raising the issue on appeal. The relation between the firearm and the underlying offense is an essential element of the crime, and failure to instruct upon it warrants reversal where there is a significant possibility the jury might have acquitted if it had considered the matter. United States v. Hudson, 564 F.2d 1377, 1380 & n. 3 (9th Cir.1977). We reverse the conviction under 18 U.S.C. § 924(c), Count 13, of the indictment.
Since there were convictions on other counts, we must address the issue of sentencing. Life imprisonment without possibility of parole is a permissible sentence under the Continuing Criminal Enter
