That's in contradiction with what a federal prosecutor says in this article: http://www.reuters.com/article/2013/08/05/us-dea-sod-idUSBRE97409R20130805 http://www.reuters.com/article/2013/08/05/us-dea-sod-idUSBRE... To quote: "In a Florida drug case he was handling, the prosecutor said, a DEA agent told him the investigation of a U.S. citizen began with a tip from an informant. When the prosecutor pressed for more information, he said, a DEA supervisor intervened and revealed that the tip had actually come through the SOD and from an NSA intercept." Admittedly you only specified the IRS and FBI so perhaps you intentionally left out the DEA.
