I don't know that many people really. My circle of friends is very small. Robert Fripp ran a human contact underground for a while in the 80's and I tapped into his school for magic dances or whatever you call Claymont, where his guitar craft seminars were.
Gabriel was just someone I interviewed for Allegheny View, our campus newspaper, but we played a little poetry game where I gave him the opening line to a poem and he completed the line.
The evidence at
texasschoolbook - Home is often assumed to be a hazing operation that was an offshoot of involvement with Claymont. Zell, who wrote the "injecting people" document was at Northeon Forest with Walter Hoderewski, who I met at Claymont.
The problem is that the way I really know Zell is through contacts in Art School that include members of a gang named in the writings of Gail Burstyn which speak of the murder of Martin Luther King and give a date for the assassination of Lennon.
They must have been surprised to get away with it so openly that their letters are in the public domain, circulated to college professors, raised with police and the FBI and I think Gabriel did just that for them by coming up with their cover story for Zell.
Nevertheless the fact remains that the comments Zell alludes to, "what would you think of a scheme to transform the human race by injecting the blood" predate the appearance of AIDS as did planning for the Mt. Desert Island entrapment operation with intent to do bloodtesting.
Schizophrenia is just one of the injuries that they inflicted as a cover operation. Oh, look at the schizoid man telling everybody what we done hahahahahahahahahahahaha.
