What is the natural and probable consequences of a crime committed by a person who knowingly aids and abets criminal conduct?

"A person who knowingly aids and abets criminal conduct is guilty of not only the intended crime but also of any other crime the perpetrator actually commits that is a natural and probable consequence of the intended crime." (People v. Mendoza (1998) 18 Cal.4th 1114, 1133; see also People v. Prettyman (1996) 14 Cal.4th 248, 260 [The natural and probable consequences doctrine "is based on the recognition that 'aiders and abettors should be responsible for the criminal harms they have naturally, probably and foreseeably put in motion."'].)
