Where must reports of suspected espionage, sabotage, terrorism, or subversive activities be submitted?

Reports of suspected espionage, sabotage, terrorism, or subversive activities must be submitted to the Federal Bureau of Investigation (FBI) because the FBI is the primary federal agency responsible for investigating and enforcing federal laws related to national security threats. The FBI has established protocols and resources to handle reports of such critical incidents, ensuring they are assessed and acted upon appropriately.

In the context of national security, the FBI works in collaboration with other agencies but serves as the lead for domestic threats and espionage cases. Their authority and expertise in these matters enable them to coordinate the response, conduct investigations, and liaise with other intelligence and law enforcement agencies. Thus, when there are suspicions of activities that could harm national security, directing reports to the FBI is crucial for effective response and prevention measures.
