Why establish a cordon around the scene?

• A. To prevent contamination and keep unauthorized personnel out.
• B. To allow media access to the area.
• C. To designate a press area.
• D. To route traffic away from the scene.

Answer: (A)

The essential aim of establishing a cordon is to protect the integrity of the scene by restricting access to authorized personnel only. By keeping unauthorized people out, investigators reduce the risk of contaminating evidence—footprints, displaced objects, or traces that could compromise findings—and they also control safety hazards within the area. This secure perimeter helps maintain the chain of custody, ensuring that any collected items can be traced back to the correct source and context. Directing media or designating a press area and routing traffic may occur as part of overall scene management, but they’re secondary to preventing contamination and ensuring safe, undisturbed work for the investigators.
