The Unloaded Gun and the Unexpected Bullet

Under the common law, assault is either an attempted battery or an intentional placing of another in apprehension of an imminent battery. The mental state for assault is purpose or knowledge with respect to the act and the resulting apprehension (or attempted battery). For assault with a deadly weapon, the prosecution must prove that Dana intentionally did an act that caused Lee to reasonably apprehend an imminent battery, or that she attempted a battery. Dana intentionally pointed the gun and pulled the trigger. She intended Lee to apprehend a battery (even as a joke), so the act was intentional. However, the key issue is whether her mistake about the gun being unloaded negates the required mental state. For assault as attempted battery, the defendant must intend to cause a battery. Dana did not intend to shoot Lee; she believed the gun was unloaded. Thus, she lacked the intent to cause a harmful or offensive contact. For assault as placing in apprehension, the intent required is that the defendant intended to cause apprehension. Dana did intend to cause apprehension (the joke), so she may be guilty of assault even if she believed the gun was unloaded, because the act was still threatening. But the deadly weapon element may require knowledge that the weapon is loaded or at least recklessness as to that fact. Under the Model Penal Code and common law, a mistake of fact negates the mental state if it is honest and reasonable. Dana's mistake was honest. Whether it was reasonable is a question for the jury. If reasonable, it negates the purpose or knowledge required for assault with a deadly weapon. Thus, the prosecution may fail to prove the required mental state for the deadly weapon enhancement, but Dana could still be guilty of simple assault if the jurisdiction recognizes assault as placing in apprehension with only intent to cause apprehension. The analysis turns on the precise mental state for the weapon element.

Battery is the unlawful application of force to another person resulting in harmful or offensive contact. The actus reus is the contact; the mens rea is generally intent to cause the contact, or criminal negligence in some jurisdictions. Under common law, battery requires intent to cause a harmful or offensive contact or apprehension thereof. Dana did not intend to cause contact; she intended only to frighten Lee. The doctrine of transferred intent does not apply because Dana had no intent to commit a battery against anyone else. However, some jurisdictions allow battery to be proven by criminal negligence. Dana's conduct in pointing a loaded gun, even believing it unloaded, may be criminally negligent if a reasonable person would have checked more carefully. The fact that she removed the cylinder and showed Lee it was empty suggests she took some care, but a reasonable person might still have verified each chamber. If the jurisdiction requires only negligence for battery, Dana could be convicted. Under the Model Penal Code, battery is not a separate offense but is covered by assault; the MPC requires purpose, knowledge, or recklessness for bodily injury. Dana was at least reckless if she consciously disregarded a substantial and unjustifiable risk that the gun was loaded. Given that she had just removed the cylinder and believed it empty, a jury could find her belief reasonable, negating recklessness. Therefore, battery conviction is uncertain and depends on the jurisdiction's mens rea requirement. The strongest argument for the prosecution is that handling a firearm in this manner is inherently risky and that Dana's failure to double-check the chamber was negligent. The defense will argue that she took reasonable steps and that the injury was an accident.
