Except you can't prove that. Are they going to directly say, Satelite XYZ in geostationary orbit was monitoring data link 111322, during which we captured intelligence on platform 2342342 which resulted in a lead then passed on to domestic intelligence agencies. Nope, not going to happen. Everyone here likes to talk about the government and their parallel construction when it supports a negative notion, yet forget that it's also a legitimate tool to protect origination sources.
