In previous courses, we've stressed the importance of preventing dirty money from entering the system. Once the cash has been placed, the process of layering can be very difficult to stop. We've looked at some of the activities that FinCEN has identified as red flags for money laundering. In this course, we're going to continue looking at red flags, but the material here will be much more technical than the basic indicators in the earlier courses and deal much more specifically with international wire transfers.
