Does Section 871(a) of the Criminal Code require a defendant to give notice of the charge under section 871 of the Civil Code of Civil Procedure?

We cannot agree. At the outset we observe that the operative key words of section 871(a)-"threat" and "willfully and knowingly"-are terms of art used in statutes too numerous to recite. Inasmuch as these terms do not change from statute to statute or indictment to indictment, they are definite enough in legal meaning to give defendant notice of the charge against her. Hamling v. United States, 418 U.S. 87, 118, 94 S.Ct. 2887, 2908, 41 L.Ed.2d 590 (1974); United States v. Trotta, 525 F.2d 1096, 1099, n.6 (2d Cir. 1975).
