Conspiracy theories (imo) are a tunnel from Hawass' bathroom...and secret operations at Giza. I'm not saying Hawass is hiding anything, and I'm not into a hate campaign against him, where do you get the idea?
I just wonder about the conclusions, and I'd like to see evidence of those claims. That's all. I think of Hawass as a serious and devouted person, who obviously is fed up with all the theories proposed by the pyramidiots.
It's possible to leave Cayce out of this, then still there are questions, but let's not forget that both Hawass and Lehner were involved in a search for the Hall of Records.
