Final answer:
Reports of suspected espionage, sabotage, terrorism, or subversive activities must be submitted to the appropriate authorities, such as the FBI or DHS. Prompt reporting is important to ensure national security and public safety.
Step-by-step explanation:
Reports of suspected espionage, sabotage, terrorism, or subversive activities must be submitted to the appropriate authorities. In the United States, such reports are typically made to agencies like the Federal Bureau of Investigation (FBI) or the Department of Homeland Security (DHS). These agencies have specialized units that handle counterintelligence and national security matters.
For example, if you suspect espionage, you would report it to the FBI. If you suspect terrorism, you would report it to the DHS. In some cases, local law enforcement agencies may also be involved depending on the nature of the activity and its jurisdiction.
It is important to report any such activities promptly, as they can pose a significant threat to national security and public safety.
