And lets face reality. The NYT in this article had access to a ton more information than the IRS did. They did an incredible job of accumulating tons of unrelated information, filings and documents. A decent amount of these filings and public records didn't even exist when the IRS was doing their audit on this stuff. They are also operating in a blackhole of information to where unless someone brings the information to them, they likely didn't know it was out there. Now that some of these agencies know what IS out there, they are going to be all over this, where the statute of limitations hasn't expired.
