with the said [victim’s] personal liberty____” We have implied that kidnapping is a crime of violence under U.S.S.G. § 4B1.2(1)(ii) because it involves a “serious potential risk of physical injury to the ... kidnapped person.” United States v. Lonczak, 993 F.2d 180, 182-83 (9th Cir.1993). In an analogous context, we explicitly held that “kidnapping entails a ‘serious potential risk of physical injury’ to the victim, making the offense a ‘violent felony1.... ” United States v. Sherbondy, 865 F.2d 996, 1009 (9th Cir.1988). That holding has been followed by other circuits which have determined that kidnapping is a “crime of violence” because it, by its very nature, involves a substantial risk of physical violence. See United States v. Kaplansky, 42 F.3d 320, 324-25 (6th Cir.1994) ; United States v. Salemi 26 F.3d 1084, 1086
