What is the required action after a bank has been robbed?

After a bank robbery, the required action is to immediately notify the FBI, regardless of which bank has been robbed. This is essential because bank robberies often fall under federal jurisdiction, particularly if the bank is federally insured. The FBI has the resources and authority to investigate these crimes effectively, and prompt reporting facilitates a faster response and potential apprehension of suspects.

Furthermore, reporting the robbery quickly helps in securing the crime scene, gathering witness statements, and collecting evidence, which are all critical for the investigation. The urgency of notifying the FBI also reflects the serious nature of bank crimes, as they can pose a significant threat to public safety and financial institutions. Other options suggest delays or conditional notifications, which could hinder the investigative process or allow suspects to escape.
