You are supporting efforts during the investigation, but when you get the money from any credit card, at your level, I guess you accept the transaction as long as there is enough money at the point of origin. That means that if I have, for example, a prepaid credit card, and I want to put money in my balance, I put in mu credit card, you verify the balance, the money is there, you take it, and there's no more investigation, regardless of the origin. Whether this origin is criminal or not, you cannot verify that.
