Nova Scotia Security Guard License Practice Exam 2026 - Free Security Guard License Practice Questions and Study Guide

A security guard plays a vital role in an investigation primarily by gathering information and providing evidence related to incidents. This involves monitoring activities within their assigned area, maintaining detailed records of events, and collecting evidence, such as photographs, video footage, or written reports, which can be crucial during an investigation. Their observations can offer context and details that significantly aid law enforcement or other investigative bodies in understanding the events that occurred.

In addition, the security guard's proximity to incidents allows them to notice things that may not be readily apparent, such as behavioral patterns or unusual actions by individuals. This collected information can lead to a more informed investigation and support the legal process if the case progresses to court.

The other options outlined in the question include activities that either go beyond the typical scope of a security guard's responsibilities or involve functions that are generally reserved for law enforcement. For instance, providing witness testimony in court and conducting interviews with suspects are duties that are usually handled by police or professional investigators. Taking legal action against offenders also falls outside a security guard’s typical role, as it is usually the responsibility of law enforcement and the legal system.
