The first paragraph of 18 U.S.C. § 2113(a) makes criminal the obtaining or attempting to obtain bank property by extortion. The typical bank extortion arises where, by telephone call or other communication, an extortionist conveys a threat to a bank official, and instructs the bank official to deliver bank funds to a specified "drop site," away from bank premises. Thus, many extortions involve no face to face confrontation. Because the bank robbery statute includes extortion and attempted extortion, the Hobbs Act should not be charged in such cases.
