Human Factors Issues in Fatal Shootings: An Analysis of Four Cases

Abstract

Four cases are summarized in which the defendant was charged with first-degree murder, but where the evidence supports a high likelihood of an accidental shooting when analyzed from a human factors perspective. Empirically based knowledge of human behavior in high stress situations is used to understand what likely happened in terms of the defendant's behavior. The handgun involved in one case is evaluated in terms of its ergonomic design deficiencies, and how those deficiencies contributed to a probable accidental shooting is explained. The need for human factors professionals to become involved in serving as expert witnesses in these types of cases is emphasized.
