Criminal activity is only successful if it is surreptitious, and not measurable. But we do know that organized crime has to launder its money if it is going to be successful, and that the size of the drug trade and other criminal activities is very great. And, therefore, the issue is very important. I've also heard the United Nations use numbers up to a trillion. I don't put a lot of basis in it.
Money laundering starts with the initial payment, say, for so much heroin.
That money basically has a velocity effect. You can count it and count it and count it, multiple times, as it runs through the criminal organization for payments and the like. So this is a tricky business. Our thinking is that the answer is yes, probably half is a reasonably good estimate. The other half goes everywhere from fraud, to extortion.
