Have you watched the Netflix Dirty Money episode about this? You might find it interesting. One of the things it claimed about what HSBC was doing was that they were simply failing to even acknowledge the flagged transactions and had a huge backlog of reports that were not only for very suspicious amounts but also transfers to/from entities that were on federal sanctions lists, and the blacklist was stupidly implemented so it could be bypassed by replacing e.g. XYZCO with XYZ-CO or XYZ.CO. Some AGs told them they had to get off their asses and start processing these reports, and they responded by hiring a sweatshop of inexperienced accountants and told them to just go through the backlog and close the reports without investigation. The show is called Dirty Money, and the episode is "Cartel Bank" from season 1.
