Is there a difference between bank robbery and attempted bank robbery?

Attempted bank robbery is covered under U.S.S.G. 2B3.1(b)(1). See U.S.S.G. 2B3.1(b)(1) (1995); United States v. Van Boom, 961 F.2d 145, 147 (9th Cir.1992). "18 U.S.C. 2113(a) defines the crime of bank robbery as committed by one who 'takes or attempts to take ... any property or money ... in the care ... of any bank.' " Van Boom, 961 F.2d at 147. Thus, bank robbery and attempted bank robbery amount to the same crime. Id.
