if someone is wiring money from a regular commercial bank lets say from argentina to the united states in small amounts, how would law enforcement start to investigate why these wires are coming in from an american citizen residing abroad? if an american citizen lives abroad and send remittances or money from abroad in small amounts less than 10k at a time, how or why would law enforcement look into this money or bank account if its in wells fargo, chase, citibank, or bank of america???? just regular commercial banking of course and nothing offshore of course........ can someone please tell me. thank you.
