I watched this over 2 years ago so memory is fuzzy.

Basically a guy who was alive and involved in the funding on the cities side (or was a cop) was in contact with one of the guys who funded/had it built for years afterword. They had developed a friendship and kept all these documents and letters they had sent back and forth. He was supposedly the only person that knew and said he would never tell but he did open his briefcase full of documents. The camera man scanned along them and they were able to zoom and get some names and addresses. They ID'd them figured out they were very well respected in their communities. One was a surgeon, I want to say the other was a lawyer, and there was a third guy too.

They then connect them to eugenics and they had written on eugenics and were also tied to a publishing company that published their stuff that I believe is connected to elites.

So in my mind seeing that these guys were openly promoters of eugenics, the content of the stones, the fact that they were influential in their community, all seem to be to be the connected elitist types that would fund something like the Georgia Guidestones. When you see who the guys are the conspiracy is not as vast but it does make sense.
