Interesting questions and unfortunately I can't answer them but I can tell you that much of his story beggars belief.
Charles said that he never dreamed of writing books. He was writing his memoirs for his Grandchildren over a several year period and when he became unemployed his wife insisted on contacting a publisher.
Among the more incredulous includes his recounts of the Tall White's (female apparently)
repeatedly picking the locks of the barracks area / "visitors center" to use the bathrooms at night! He even said his predecessor told him "White Ghosts" haunted the place.
The Tall White children being entertained by watching him float weather balloons (while they floated about in glowing anti-gravity suits).
Watching the Tall White's (escorted by a contingent of CIA and Tall White guards) walk into
a Vegas casino while dressed as humans complete with make up.
The Tall White females are wildly interested in the latest fashion catalogs and love pouring over them.
The Tall White's and the Greys have an intense dislike and barely tolerate each other.
There's much, much more that's quite hard to swallow.
But I can tell you that if he's making this up, he should be in the movies as he acts as though he's telling the truth and even takes any impromptu question anyone cares to ask and there were plenty from an obviously skeptical group when I attended.
I've been quite disturbed since attending his lecture. I've reminded myself that there's virtually no evidence of any kind to support his singular account and even David Hilton's "evidence" is anecdotal at best. I've recalled some of the more seemingly preposterous parts of his story in an effort to discount him and tried to admire his creative mind (his books were published as fiction), and yet, it's been difficult to do.
There's a ring of truth about it. His sincerity seems unquestionable. If he's lying, it's obvious he believes it to be true and while it would be easy to think he's nuts, he seems not only very sane but also very intellectual and philosophical.
And that is what's so disturbing.
I comfort myself by hoping I'm wrong and that Hall is simply a brilliantly creative liar who has concocted a "Whale-of-a-tale" that I've foolishly fallen for.
Unfortunately, I think it's more likely he's telling the truth.
