Now that I'm not posting on my phone I can give a bit more detail.
I'm not going to reproduce it verbatim to avoid copyright isses, but you can read the bulk of the allegations made in Sibrel's book here:
https://stratagemsoftheright.blogspot.com/2021/09/exposing-lyndon-johnsons-apollo-fraud.htmlSearch for the following text to get to the meat of it and avoid Sibrel's fantasy life of CIA abduction and men in black skullduggery (and his flat out lie that Armstrong confessed to him privately just before conveniently dying):
"Now I have something major to disclose"
These are the same allegations repeated almost verbatim by the person in the video.
Now, Sibrel presents his story as if it was recounted to him in person, whereas this video makes it clear that it was "My dad told me...". He was also the one who supposedly contacted Bart.
He also claims that the person involved, now supposedly identified as Cyrus Eugene Akers, was the "Chief of Security" at the base. Akers' own gravestone (not hard to find) identifies him as a staff sergeant in the Air Police. Those are the first easy holes to pick in the story.
