Is appellant liable as a result of the Attorney General's argument that appellant acted as an aider and abettor?

The Attorney General's alternative theory - that appellant acted as an aider and abettor - gains more traction. To be liable as an aider and abettor, a person must knowingly intend to further the perpetrator's unlawful act and assist him in that act. (People v. Lopez (2013) 56 Cal.4th 1028, 1069.) It is not enough that the person simply wants to help the perpetrator achieve his unlawful ends; rather, he must intentionally contribute to the achievement of those ends. (People v. Montoya (1994) 7 Cal.4th 1027, 1039.)
