The key to laundering money is to use the right soap.
Bars and restaurants are excellent places to do that, particularly if they have video poker machines. Put some money in the machine, play a few low bid games, cash back out, the money is now clean. This only works for relatively small amounts of money, it would be a real bitch to try to clean a million dollars this way. But nobody is really auditing the books to track whether a business is profitable or not. Have you watched The Soprano’s? Bada Bing.
And really this applies to many other business’. The IRS cannot keep up with auditing small, or even large business’, not enough manpower. Some people assume that everything is watched, but it is not.
Money laundering is only a real problem at the higher levels with large amounts of money. When it involves large amounts of money that are in banks or other financial intuitions, that is a problem because transactions are reported. Large amounts of cash are a problem. This is why the US government keeps redesigning paper money, like hundred dollar bills, on a fairly regular basis. I expect that Benjamin’s to be redesigned soon. Perhaps to honor some other historical figure who has been passed over, but that is not the real reason.
Which brings us back to the IRS and nobody really watching. Because they can’t keep up. They may eventually find something to put up a red flag about, the the people involved have moved on. Small people and business’ get caught, large companies rarely do.
