Farnsworth, 92 F.3d 1001, 1008 (10th Cir.1996). The court examines “the statutory elements of the crime.” United States v. Zamora, 222 F.3d 756, 764 (10th Cir.), cert. denied, —- U.S. -, 121 S.Ct. 641, 148 L.Ed.2d 547 (2000). If the statute is ambiguous, or broad enough to encompass both violent and nonviolent crimes, a court can look beyond the statute “to certain records of the prior proceeding, such as the charging documents, the judgment, any plea thereto, and findings by the court.” Id. The statutory basis of the conviction in question is 26 U.S.C. § 5861(d), whic 91) (<HOLDING>). We join these circuits in holding that
