Early comment—it looks like Greer has tapped into the main vein—including the Secret Space Program.
So far (half hour in) his statements appear to be factual.
My issue with him remains that he overstates his own role in collecting and disseminating information—the guy has an ego the size of Mt. Everest.
I get it... But he really does have the qualifications and background to rightfully boast an ego...
Ego or not... He is shooting straight about all the factors in this interview. This one greatly added to my own knowledge base on the topic.
