He has no evidence and he isn’t exactly impartial. He retired from the CIA in the early 80s. His contractor status likely applies to unique medical-related cases and threats of national security in the UFO world.
Most of his time 80-90%+ is spent on normal medical and academic work. Yes he introduced Hal Puthoff to Tom DeLonge but even after 30+ years Kit doesn’t know if Uri Gellar is real. And Hal hasn’t produced anything legitimate that’s publicly known. If he’s a super talented government contractor, then why’s he working for a stock scammer? Why not work for the government full-time or one of the few billionaires who invested with him decades ago?
