Which action is described as securing the crime scene?

• A. Document the scene after aiding the victim
• B. Restricting access to unauthorized personnel
• C. Letting bystanders cross the perimeter
• D. Tape off the area or create a perimeter or barrier with physical barriers

Answer: (D)

Securing a crime scene means establishing a boundary to prevent contamination and preserve evidence. The most direct way to do this is to create a visible perimeter with tape or other physical barriers, so no one unauthorized enters and the area remains intact for investigators. While restricting access is part of securing, the act of physically marking off the scene with a barrier provides an immediate, clear control that reduces the risk of disturbance. Documenting the scene after aiding the victim is about processing and recording, not preventing disturbance, and letting bystanders cross the perimeter directly undermines security.
