But UFOs don’t exist! Or so we were told for decades. My guess is that the government knows that the UFO phenomena is not entirely benign but does not want to alarm the public. The report, even in unredacted form, is just another level of obfuscation on the way to a slow, partial reveal made necessary by the growing sophistication of camera and imaging technology in civilian hands.
Washington derives its power by keeping the public perpetually alarmed. So whatever the reason is, that isn’t it.
