I know some pretty sharp folks who fork for various police departments chasing illicit crypto related activity. The amount of stuff they can track including timing of transactions, entry and exit points, etc, and so over a long period of time means that most of the traditional anyonmization methods like tumblers simply do not work. Eventually someone, somewhere makes a mistake and the transactions and wallets can be traced.
If you have dirty money to hide, it's much better to hide it in a bank in Panama, or fill a sports bag with gold bars and fly it out on your private jet than use crypto.
Anything you can do from your bedroom, police can track from theirs.
I am working to track and trace and time transactions and while this is possible when and if you know the identity of at least one participant it’s quite another thing when no identity is known at all. Criminals know that so it’s notoriously hard to pull off. Thanks to Daleware secrecy and lax Super PAC rules to disclose sources of funds it’s not going to get easier.
So either your friends are genius saucers or they have effective government intelligence that would be highly appreciated. I’d be interested.
You are spot on regarding the bedroom though. Exporting physical USD is far more lucrative, by the shipload, often by Chinese Money Laundering Organisations, for free.
Including sending and receiving Monero? (This is a serious question; I don't have a perspective on this yet.)

This is why I have tape covering my webcam and music blaring. Oh, wait, that's not what you meant.
By definition the police only ever detect and catch those they are capable of detecting and catching. It's entirely in their interest to let people believe their capabilities are much greater than they really are. That goes double for the companies that sell this technology to the police.
