I can't embed the presentation made in 1989 by John Keel but it's a must see with first class visuals including the Maury island incident's Fred Lee Crisman, Men in Black, UFO and JFK connection which is my greatest example of the Tricksters being able to hack time. It's the only plausible explanation.
John Kiehl (Keel) comes from that line of investigators like Nick Redfern who knock on doors and ask people if they're prepared to speak. This presentation compliments my Men In Black post and the Maury Island Incident for excellent triangulation.
Go hear to listen and watch.
