> So you need to operate a business that also deals largely in cash, slip your illicit cash into the businesses’ revenue, cook the books and make it look like the money came from your legitimate business and not your illegitimate one, and Bob’s your uncle, at least in theory. In practice, legitimate cash businesses are more and more rare as time goes on, and investigators are really good at noticing when some random nail salon or bar has a lot more revenue than they should. I actually worked for 8 months as an intern at Fintrac, Canada's financial intel agency. This was 14 years ago now, but back then they were actually pretty good at what they did, for a group with ~300 people. They just had analysts going through vast amounts of data manually, but with plans to improve the tooling, automate more. I can only guess at how far along they've come now. The reality is, if you're moving more money than you should you'll get it caught eventually. And the more you're moving, the more likely you are to be noticed.
