I don't disagree about the SAR filing in any of these circumstances. I just read Diputs post a little different and I was just trying to understand how the transactions were being conducted. Was the customers account at the bank involved or did the customer tell someone at the bank they were doing this? If it was just something the customer said to an employee, but a review of the account doesn't show any checks written, transfers, withdrawals, etc, does that change anything? I mean what if they're doing this with money they already have in their home or something, does the bank still file a SAR? If the bank has knowledge, but can't find record or see any transactions? I'm not saying that the bank shouldn't file in that circumstance, but I don't know. I just want to understand for myself how it should be handled.
