Prepared by the District of Columbia Street Law Project for its annual city-wide mock trial competition, this instructional handout provides material for a murder trial. The defendant shot the victim in the course of a violent dispute. The prosecution charges murder while the defendant claims to have acted in self-defense. The handout clarifies the laws and explains the legal precedents. As evidence, the handout provides witness statements from a bartender and waiter who witnessed the beginning of the dispute, the arresting officer, neighbors who heard the dispute, and the defendant. Through participation in mock trials and analysis of the activity, students gain an insider's perspective on courtroom procedure and a basic understanding of the legal mechanism through which society resolves its disputes. Mock trials develop critical analysis, questioning and listening skills, and skills in preparing and organizing materials. (JD)
