Is a person who aids and abets in the commission of a crime a principal and is as guilty as a perpetrator?

The court properly instructed the jury that a person who aids and abets in the commission of a crime is regarded as a principal and is as guilty as the perpetrator. (CALJIC No. 3.00.) It also properly instructed the jury that in order to aid and abet in the commission of a crime a person must act with both knowledge of the unlawful purpose of the perpetrator, and the intent to commit, encourage or facilitate the commission of the offense. (CALJIC No. 3.01; People v. Beeman (1984) 35 Cal.3d 547, 560, 199 Cal.Rptr. 60, 674 P.2d 1318.)
