None of you have grasped the nettle as to what is going on here. Many of the governments of the Western world decided to make the banks unpaid watchmasters over the movement of money. How did they do this? By prosecuting and fining the banks over money laundering cases by saying that the banks "must have known" or "should have known" or "should have been suspicious of the amounts of maney being moved" etc, etc.
As a result, the banks now ask "what's this for?" when you want to do a large wire transfer or ask for a large wedge of cash to hit a gun show. The beauty of this for the various governments and their LE branches is that they don't have to pay for the data collection and its storage. The banks do it for them for free!! When they want to get into how an individual is moving money, they just get a warrant for their account information and read everything the bank collected for them. Easy-peasy, lemon-squeezy.
I have a wedge of money still sitting in a UK account. At some point I'll pull that money over here, probably when the exchange rate improves. No doubt I will be asked "what's the money for?". At this point I have two choices, say something tame like "I found the perfect Maserati at last" or "I'm paying off my house". But the little red guy on my shoulder says I should tell the bank that I have a terminal disease and I am treating my buddies to a farewell party. First, there will be a bunch of machine gun fun followed by a trip to the brothel over at Pahrump with all the girls and blow they can take. Then I'll tell the bank, "Oh, and all that is legal in my state". It's bloody tempting, I tell ya.
