If Monsignor Scarano, the senior Vatican official incarcerated in a Rome prison, facing money laundering charges, is typical of those in Vatican City who are in charge of financial affairs, then they need a tutorial in Money Laundering 101. Scarano has reportedly sent a note to the Pope, denying that he was engaged in money laundering, and asserting that he "tried to help someone who asked for help."
If someone asks you to help them bulk cash smuggle twenty million Euros in from Switzerland, and you find nothing wrong with that request, then you should not hold a position of financial responsibility anywhere. Obviously, the experts hired to bring Vatican City into compliance with banking best practices have their work cut out for them. Could they please schedule mandatory, universal lectures there, at their earliest convenience ?
