Which of the following is NOT a responsibility of a security guard at a crime scene?

1. Controlling access to the scene

2. Collecting evidence

3. Documenting the scene

4. Coaching bystanders on their behavior

The correct answer is: Coaching bystanders on their behavior

In the context of a crime scene, a security guard’s primary responsibilities are generally focused on ensuring the safety and integrity of the scene. This includes controlling access to the area to prevent contamination or interference, as well as documenting the situation in a way that supports the ongoing investigation. Collecting evidence is typically the responsibility of law enforcement professionals rather than security personnel. Security guards play an ancillary role in this regard; they might support evidence preservation by restricting access but do not actively collect evidence themselves. Documenting the scene, which might include taking notes or making observations that can later aid investigators, also falls more within the duties of law enforcement but is still relevant for a security guard to some extent. Coaching bystanders on their behavior, however, is not a formal or recognized duty of a security guard at a crime scene. While security personnel may provide direction to ensure safety, their main focus should be on access control and scene preservation, thereby allowing trained investigators to handle specific tasks related to the evidence and the legal procedures following a crime. This demarcation of responsibilities helps maintain an orderly and secure environment for professional law enforcement to operate effectively.
