Which of the following roles does a security officer NOT typically assume?

In the context of a security officer's typical responsibilities, conducting formal investigations is generally not a primary role. Security officers are tasked with monitoring access to facilities, enforcing rules and regulations, and providing emergency first aid as needed. These duties revolve around maintaining safety and security rather than conducting in-depth investigations.

Formal investigations usually fall under the jurisdiction of law enforcement or specialized investigators who possess the training and authority required to gather evidence, interview witnesses, and compile reports for legal proceedings. While security officers may observe and report incidents that could warrant an investigation, the action of formally investigating is outside their scope of training and responsibility. This distinction is essential for understanding the boundaries of a security officer's role and the importance of collaboration with law enforcement when necessary.
