Almost all the cases studied involved women who killed men to whom they were married or with whom they lived in an intimate relationship. The men they killed had beaten and abused them in the past and were assaulting or threatening to assault them again. In some cases the women, after years of brutality and despairing of stopping the beatings or escaping their mates, killed their mates when they were off-guard. The outcome of all the cases was similar. The woman was arrested immediately and charged with murder. She subsequently pleaded guilty to murder or manslaughter, hoping that case circumstances would move the judge to leniency; or she went to trial, was duly convicted, and sent to prison. In either case, she was judged guilty of a serious crime. This plight of abused women who kill their abusing mates stems from a combination of two factors. First, the law of self-defense or justifiable homicide reflects masculine assumptions about the circumstances that entitle a person to act in self-defense. The second factor is society's ambivalent and biased attitudes about women and its acceptance of violence against them. This book recommends reform in the following areas of self-defense law: the easing or abandonment of the requirements of equal force, imminent danger, retreat, and reasonableness; the use of expert testimony on the mental states of battered women; and the right to use deadly force in defense against rape.
