Financial Crimes Enforcement Network
Hell no, I never heard of them until like, early April?...just dropping a quick primer here on who they are/what they do, for my fellow "oh, I did not know that!" peeps, eh?
FinCEN is a bureau of the U.S. Department of the Treasury. The Director of FinCEN is appointed by the Secretary of the Treasury and reports to the Treasury Under Secretary for Terrorism and Financial Intelligence. FinCENs mission is to safeguard the financial system from illicit use and combat money laundering and promote national security through the collection, analysis, and dissemination of financial intelligence and strategic use of financial authorities.
FinCEN carries out its mission by receiving and maintaining financial transactions data; analyzing and disseminating that data for law enforcement purposes; and building global cooperation with counterpart organizations in other countries and with international bodies.
