A crime documentary is a non-fiction film or television program that explores real criminal cases, events, or issues. These documentaries often include interviews with law enforcement officials, witnesses, and sometimes even the criminals themselves. They aim to provide insight into the circumstances surrounding the crime, the investigation process, and the impact on victims and society. Typically, crime documentaries use a mix of archival footage, photographs, and reenactments to tell their stories. Popular examples include documentaries about infamous cases like Ted Bundy or the Zodiac Killer. They can also address broader topics such as criminal justice and forensic science.
