Final answer:
The exact number of officers required is not provided due to lack of specific protocol context. However, similar operations like FDIC bank examinations ensure financial stability and insured depositor funds up to $250,000.
Step-by-step explanation:
The question does not provide sufficient context to determine the exact number of officers required for transportation and observation of seized cash when the amount exceeds $15,000. Such procedures would typically be outlined in law enforcement or financial institution protocols and can vary by jurisdiction. In relation to FDIC procedures, however, it is noted that bank examiners evaluate the banks' balance sheets and provide deposit insurance to guarantee depositor funds up to $250,000 per account. This insurance helps prevent bank runs and ensures the stability of the financial institutions.
