What should be established when noting "how" an event occurred?

Establishing the sequence of events as told by witnesses is crucial in understanding "how" an event occurred. This process involves gathering firsthand accounts and testimonies from those who witnessed the incident, which helps create a clear timeline and context for the event. By compiling these statements, investigators can piece together the facts leading up to and following the occurrence, which provides insights into causation and motivation, ultimately enhancing the security officer's situational awareness and response strategy.

Witness testimony is often the most immediate and relevant source of information regarding an event, as it captures the perspectives and observations of individuals who were present. Their accounts contribute significantly to the overall understanding of the event and can aid in identifying patterns, uncovering underlying issues, and ensuring that security measures are appropriately tailored to mitigate future risks.
