Does an open-ended indictment need to be amended or amended?

7 An indictment cannot be completely open-ended, see United States v. Cecil, 608 F.2d 1294, 1296-97 (9th Cir.1979), but the indictments in this case were sufficiently specific to apprise appellants of the charged offenses and enable them to prepare a defense. There was no infirmity in their language. See United States v. Tavelman, 650 F.2d 1133, 1137-38 (9th Cir.1981), cert. denied, 455 U.S. 939, 102 S.Ct. 1429, 71 L.Ed.2d 649 (1982).

8 Bump's other arguments against admission of these items do not merit discussion.
