What is the burden of establishing guilt beyond a reasonable doubt?

determines whether the People have met the burden of establishing guilt beyond a reasonable doubt. If the trier of fact's findings are reasonably justified under the circumstances, the opinion of the reviewing court that the circumstances may also be reconciled with a contrary finding does not warrant reversal of the judgment. (People v. Casares (2016) 62 Cal.4th 808, 823-824.) After reviewing the evidence in the light most favorable to the prosecution, we determine whether any rational trier of fact could have found the essential elements of the crime beyond a reasonable doubt. (People v. Rangel (2016) 62 Cal.4th 1192, 1212-1213.)
