the dilemma
I think the bank is okay to advise clients of the 10,000 paperwork and the clients can withdraw $9999 every day as long as it is for a legal purpose. On the other hand, if the money is routinely used for illegal purposes, money laundering comes into play. The wise Prince keeps lots of cash in a home safe. :)
I could be wrong and there are always hundreds of legal traps and shots for both sides.
Look at what they are doing to Martha Stewart. If enough powerful people want to get you, they may not succeed if you are rich enough but they can make your life hell for a long time.
