Kindly, you know little about intelligence. Imagine if they were given up by a human source. That kind of thing doesn't leak until everyone is dead and buried, and even then it doesn't always get out because it gives foreign counterintelligence services some ability to assess the damage done by the source. Imagine if they were given up by a technical collection program. Same thing.
