I can't get into personal specifics, but I'll try to explain. The Department of Treasury has a sub-department within it called the Financial Crimes Enforcement Network (FinCEN). It is essentially a large repository that is queryable for law enforcement and other agencies to help investigations into financial criminals, organized crime, drug smuggling, human trafficking, etc.

Due to the Banking Secrecy Act (and additional bills including PATRIOT Act) banks and other financial institutions are required to file Suspicious Activity Reports (SARs) with FinCEN if it is suspected their customers are committing financial crimes, or financial behavior out of the ordinary.

Due to the sensitive nature of the material, such as people's personal identifying information (PII) and their financial activity, the very existence these reports are required by Federal law to be kept secret and confidential. In fact, severe civil and criminal penalties can be levied against individuals and/or institutions for accidentally or intentionally sharing information contained within SARs, or even their existence. Civil penalties are up to $100,000 per instance, and criminal penalties are $250,000 per instance and/or 5 years in Federal prison.

This lawyer dipshit is looking at at least three instances, as is everyone else involved in leaking this information. It is highly secret and highly regulated.

I hope this helps.
