Can a defendant be punished multiple times for a single act or omission?

Section 654 precludes multiple punishment for a single act or omission, or an indivisible course of conduct. Under California law, it is the defendant's intent and objective that determines whether the course of conduct is indivisible. Thus, if "'"all of the offenses were merely incidental to, or were the means of accomplishing or facilitating one objective, defendant may be found to have harbored a single intent and therefore may be punished only once."'
