One of the most significant money launderers is a famous attorney from Shearman and Sterling in NYC.
From my experience, prominent financial executives attempted to engage in blatant laundering of drug money in BVI. These individuals were connected to the attorney and one is a public official appointed by 4 US Presidents.
This was 20+ years ago and I don’t know what they actually did, but I was in the room when they tried to do it. Outside the room hung a giant photo of George W. Bush golfing with the firm’s CEO.
They offered me $1 million in cash to fly with $100m at a time to Tortola. The financial structure was created by the attorney.
