This is the most closely related thread on the board, apologies if this is too far off topic.
Noticed while reading about the NSA's Solar Wind program for an unrelated project.
Stellar wind is the program following thin thread, Bill Binney's mass collection program.The claim is that NSA passed tips gleaned from stellar wind to FBI for follow up. FBI then returned a large percentage as dead-ends or "pizza cases". The implied meaning is obviously that suspicious communications were just pizza delivery orders. Everything we know about the Stellar wind project makes that seem unlikely, add to that the use of "pizza" by the same people who officially documented the lexicon for pedos.
