How does Section 654 of the California Criminal Code apply when a defendant has only a single intent and objective?

"Section 654 precludes multiple punishment where an act or course of conduct violates more than one criminal statute but a defendant has only a single intent and objective." (People v. McCoy (2012) 208 Cal.App.4th 1333, 1338.) If the statute applies, the trial court must impose sentence but stay execution on all convictions except the one carrying the longest sentence. (Ibid.) We review explicit or implicit factual resolutions of the trial court for substantial evidence in the trial record, which the court may base on any facts in the record without regard to the verdicts unless the verdicts foreclose the consideration of them in some fashion. (Id. at pp. 1338, 1340.)
