Which of these is not reported through information systems to the FBI?

Emergency evacuation procedures are typically internal protocols developed by organizations to ensure safety during specific situations, such as natural disasters, fires, or security threats. These procedures focus on facilitating the immediate safety of personnel and are not incidents or activities that warrant reporting to law enforcement or intelligence agencies such as the FBI.

In contrast, probable espionage, possible acts of sabotage, and subversive activities are all security threats that can potentially affect national security and might require notification to the FBI. These activities are linked to insider threats and can have implications for the wider security environment, prompting the need for reporting through the appropriate channels. Therefore, the distinction lies in the nature of the information; emergency evacuation procedures pertain to safety protocols rather than criminal or threatening actions.
