Can a felon in possession of a firearm be punished for two armed robberies?

In People v. Ratcliff (1990) 223 Cal.App.3d 1401, 1413, the court held that the defendant could be punished for being a felon in possession of a firearm and for two robberies where his possession of the gun "continued before, during and after [the robberies]." In that case, the defendant robbed a victim with a gun, committed a second robbery with the gun an hour and one-half later, and was arrested one-half hour later while still in possession of the gun. (Id. at pp. 1404-1405, 1413.)
