In Vidal the Court recognized that the California definition of aiding and abetting includes "encouragement," which in California includes "promotion and instigation." In California, A person may be considered an aider and abettor if he/she acts "with knowledge of the criminal purpose of the perpetrator and with an intent or purpose of either committing, or of encouraging or facilitating commission of, the offense." People v. Beeman, 35 Cal.3d 547, 560 (1984). See also, People v. Prettyman, 14 Cal. 4th 248 (1996).      This is language in not included in the Federal definition aiding and abetting, and one can argue that the California definition of aiding and abetting is broader than the federal definition.      In Vidal, the Ninth Circuit neglected to explain how the federal definition of aiding and abetting" addresses the issue of "encouraging." It only relies on the language of jury instructions related to 18 U.S.C.S. 2(a) aiding and abetting and the decision in United States v. Barnett, 667 F.2d 835 (9th Cir. 1982). However, the Barnett decisions inclusion of the words "otherwise encourages" in its definition of "abettor" is only in passing. The facts of the case do not specifically relate to an aider-abettor who only "encouraged." The defendant in Barnett gave information to the co-defendant as to where the co-defendant could obtain certain illegal substances. Arguably, this action was more than just passively supporting the co-defendant in perpetrating the crime. Thanks to Kathy Brady.
