How has the court treated the argument that only one volitional act gives rise to multiple offenses?

The court rejected the argument, stating that "this was not a case where only one volitional act gave rise to multiple offenses. Each shot required a separate trigger pull. All three assaults were volitional and calculated, and were separated by periods of time during which reflection was possible. None was spontaneous or uncontrollable. '[D]efendant should . . . not be rewarded where, instead of taking advantage of an opportunity to walk away from the victim, he voluntarily resumed his . . . assaultive behavior.'
