Does section 654, subdivision (a) of the California Criminal Code bar a defendant from being punished for more than one crime?

Section 654, subdivision (a) provides: "An act or omission that is punishable in different ways by different provisions of law shall be punished under the provision that provides for the longest potential term of imprisonment, but in no case shall the act or omission be punished under more than one provision." Judicial interpretation holds that section 654 also bars multiple punishment for separate offenses which are committed during an indivisible course of conduct, i.e., with a single criminal intent or objective. "'Whether a course of criminal conduct is divisible and therefore gives rise to more than one act within the meaning of section 654 depends on the intent and objective of the actor. If all of the offenses were incident to one objective, the defendant may be punished for any one of such offenses but not for more than one.' [Citation.]" (People v.
