On July 25, Miami-Dade Florida circuit judge Teresa Pooler dismissed money-laundering charges against Michell Espinoza, a local bitcoin seller. The decision is a welcome pause on the road to financial serfdom. It is a small setback for authorities who want to fight crime (victimless or otherwise) by criminalizing and tracking the “laundering” of the proceeds, and who unreasonably want to do the tracking by eliminating citizens’ financial privacy, that is, by unrestricted tracking of their subjects’ financial accounts and activities. The US Treasury’s Financial Crimes Enforcement Network (FinCEN) is today the headquarters of such efforts.
As an Atlanta Fed primer reminds us, the authorities’ efforts are built upon the Banking Secrecy Act (BSA) of 1970. (A franker label would be the Banking Anti-Secrecy Act). The Act has been supplemented and amended many times by Congress, particularly by Title III of the USA PATRIOT Act of 2001, and expanded by diktats of the Federal Reserve and FinCEN. The laws and regulations on the books today have “established requirements for recordkeeping and reporting of specific transactions, including the identity of an individual engaged in the transaction by banks and other FIs [financial institutions].” These requirements are collectively known as Anti-Money-Laundering (AML) rules.
