The Central Intelligence Agency or better known as the C.I.A. has finally revealed the truth about aliens or extraterrestrials, a long time ago, already. They have shown all(or is it?) papers they have about U.F.O.s and I believe there is no possibility of this being a hoax. Why would they waste their time, creating these just to fool us?
In 1999, the U.S. government paid the Zapruder family US $16 million for the film of JFK's assassination. This also has a connection to the CIA, as well. Here's a silent, short film of JFK's assassination, filmed by Abraham Zapruder who is a private citizen:
It is true that we do not know much about Area 51 or aliens, but there is no real proof that the JFK assassination had to do with the quote of him asking for proof of aliens. For all we know, we still don't know if aliens are out there. We all know from the stories that Harvey Lee Oswald or whatever his name was assassinated JFK because of angry reasons. It was most likely a coincidence that this had ever happened.
There might be no existing proof of JFK demanding for the release of UFO and has no connection to the assassination of JFK, but there is a genuine evidence of a memo from National Security Agency to John F. Kennedy, regarding this.
Well if the NSA didn't want us finding it, why put it up in the first place? I'm quite certain that what happened when JFK died was because of rage out of Harvey Lee Oswald. No Aliens, no random quotes, just rage. That's it. We don't even know if aliens even exist, so there you have it. The truth is that Harvey Lee Oswald killed JFK because of rage.
