This is an interesting read. I don't know how much of it is true though. About the US government's involvement in seeing, finding, and investigating UFOs, particularly here in this country and the Top Secret departments created to gather that information....namely something called Majestic-12 pr MJ-12. This book purports that President John F. Kennedy was assassinated at the direction of MJ-12 because he was pushing to know about this group and to put control of the UFO information under the Office of the President. When JFK took office, former Pres. Eisenhower told him about what he had also learned about the secret, off the books group. When President, Eisenhower had threatened to send in the First Army to invade the location in NMex, but never did. MJ-12 under no circumstances was going to give up their total control. Since the Warren Commission only theorized who was responsible, it is anyone's guess. The book did include photocopies of official top secret documents confirming a planned assassination (actually using the word "assassination"), it's probably but still not absolutely confirmed. But since none of the other theories are certain either....who really knows?
