What is the purpose of scene control as part of a crime scene safety plan?

• A. To prevent contamination, ensure safety, and preserve evidence.
• B. To keep spectators out of interviews.
• C. To speed up evacuation.
• D. To establish a press briefing area.

Answer: (A)

Scene control is about protecting the integrity of the crime scene while responders work. The key purpose is to prevent contamination, keep people safe, and preserve evidence for analysis and the investigation. This means establishing a secure perimeter, controlling who can enter and exit, and documenting every movement into and out of the area. It also involves using appropriate protective equipment, minimizing unnecessary disturbance, and avoiding actions that could alter or destroy physical traces. By maintaining order and safety at the scene, investigators can preserve the chain of custody and ensure that any evidence collected remains admissible and reliable.

The other options relate to different aspects of response—keeping spectators out of interviews, speeding up evacuation, or setting up a press briefing area—but they do not capture the primary purpose of scene control, which centers on safeguarding the scene and its evidence.
