This is not the only situation where investigators are hiding iffy information sources, and committing perjury. We all know about deals with informants, who sometimes receive immunity for major crimes, in exchange for their information.
But the elephant in the corner is DEA's Special Operations Division (SOD).[0] This funnels information from the CIA and NSA to the FBI, IRS, DHS and USCIS. But you will find nothing about SOD in any of the cases where it reportedly played a key role (according to that DEA Museum lecture).
Anyway, there's no evidence that SOD has ever been used except for major drug cases. But there's no reason to assume that it hasn't been, either.
