Hi iainl140285,
All is not what it seems.
Barry M. King did indeed make CDs and VHS video tapes which he sold in various UFO magazines, even published his own magazine, which was described as some as 'bizarre' during the 80s.
You can see this material on Youtube. It's this material that he offers. I suggest that you carefully scrutinize each and every video, even the 'documentation' that is revealed in one of them with the stock 'ET photo'.
Nothing wrong with that I suppose.
He also endorses a book "Cosmic Top Secret" by a guy called Jon King (apparently no relation) who also published a UFO magazine called UFO Reality, also around the same time period, late 80s early 90s. He claimed that, "A large triangular area of South-West England, centred on Barbury Castle, would be receiving "energy codings" to prepare humanity for ET contact between 1998 and 2013, by which time the dimensional shift will have occurred." By the way the book costs 25 quid.
Any similarities between James Casbolt, Barry King and Jon King are merely coincidental.
So, to conclude, your assumption that Mr. King created these CDs etc. free of charge to get the word out, is not strictly correct.
One could be forgiven in thinking that his recent publications are just copies of is old 'works' that have stopped selling.
But then I'm just a cynic and I'm sure, there's nothing wrong with that either.
Best regards,
Steve
