Interesting video from Naomi Brockwell
tl;dr is all banks reports suspicious transactions, they tend to overreport, and thr Law prevents them telling you they did.
Having worked in the corporate security wing of a national bank, I can confirm this video is fairly accurate. I’ve had experiences where I’ve spoken directly with people from a whole spectrum of federal law enforcement agencies (FBI, HSI, USSS, IRS-CID, etc) that had instant access to these SARs in what I can only assume is a database administered by FinCEN. When I tried to probe for details about this system, even with agents whom I had a good rapport with, they were extremely tight lipped about how it worked.
Good video, hopefully this doesn’t come as a surprise to anyone. The only 100% anonymous payment system is cash. Also related:
