monitor Dollars that are being sent through Narcotraffic inside Peru and cleaned inside the Banking system as laundry.

Narcotraffic acts similar like the Federal Reserve and introduce through their system, millions of dollars inside the banking system of Perú: Those Dollars are "without origin".
Having said the above, Perú Banking system is a "Second Federal Reserve" in the shadow.
Banco Central de Reserva (BCR) needs to buy/sell millions of Dollars frequently in order to maintain the Peruvian currency (Nuevo Sol) stabilized.
Public opinion wants to Audit the FED. What about auditing the "FED in the Shadow".
The Laundry of Dollars through/inside the economy of a third Country is a big "Leak" to be solved.
