Michael Moore takes on the participatory role in his documentary "Bowling for Columbine" by directly interviewing people on camera. He presents himself as an average person to appear more trustworthy to the audience. Throughout the film, Moore maintains his viewpoint that guns lead to negative consequences, though he explores different reasons for gun violence. Elements like Moore addressing the camera or using shocking footage are meant to draw attention to the investigative nature of the documentary and force the audience to see the issues through Moore's perspective. However, some context may be omitted or manipulated to strengthen Moore's arguments.
