A lot to untease in that post, this stood out too:  From an intelligence perspective, you have a problem where you need to convince people to defy common sense and keep secrets. The best way to do this is to recruit cultists who are blindly obedient. To that end, Tavistock and others created fake cults that were specifically designed to infiltrate other cults. One example is the Process Church of Final Judgment. Tavistock created this fake cult whose theology was to combine all the god forms into one person (yourself). The Process church infiltrated Scientology, right away. Then, the Bohemian Grove and the Manson cult. They eventually co-opted Santa Muerta cults in Mexico before moving onto Voodoo cults in the Caribbean. Their theology, or a close facsimile, now rules a number of cults for the Crown, where the occultists, themselves, are dupes.  I started reading about the speculations over a Son of Sam Cult and they mention similar things.  Around the time that Yonkers resident David Berkowitz, aka Son of Sam, committed his first murder, Untermyer Park was allegedly used by a kind of Satanic cult that performed mystical rites there, perhaps even blood sacrifice. Even though it has never been officially confirmed, the cult that held its séances in Untermyer park was believed to be an offshoot of the notorious Process Church of the Final Judgment, which also had ties to the Manson Family. The Process Church was founded in London in 1966 by Robert de Grimston and Mary Ann Maclean, both of them former Scientologists, preaching that God is made up of Christ, Jehovah, Lucifer, and Satan. Theories about the Process Church range from diabolical Satanists overseeing webs of influence to 1960s meddlers in the occult who quickly abandoned their cause. Reportedly the Process morphed into an animal shelter charity and Robert de Grimston changed his name and became a postal worker on Staten Island.  After I learned about Michael Alig's backstory, I believe there's a connection to cult groups, organized crime and the 'Drag Kid' (groomed for pedophiles) and transchildren recruiting (for purposes of sexual mutilation/medical experimentation).   Some people also speculate that Untermyer Park was a front for arranging murders by/for members of organized crime.
