Does Section 654, subdivision (a) of the California Criminal Code prohibit punishment for two crimes arising from a single, indivisible course of conduct?

Section 654, subdivision (a) provides in pertinent part: "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." The purpose of this statute is to ensure that punishment will be commensurate with culpability. (People v. Trotter (1992) 7 Cal.App.4th 363, 367.) It "prohibits punishment for two crimes arising from a single, indivisible course of conduct. [Citation.]" (People v. Islas (2012) 210 Cal.App.4th 116, 129, citing People v. Latimer (1993) 5 Cal.4th 1203, 1208.)
