Like I said, the guy makes some interesting claims, but after looking at his stuff for a few minutes I concluded he was a man on a soap-box more than a whistle-blower. I youtube searched the guy's name and came up with a congressional hearing of sorts, although it didn't cite when or where this happened and who invited him to speak.
They gave him about twenty minutes. Of that time he spent perhaps five talking about what he was "whistle-blowing" and fifteen talking about the "kabal" shadow government or our need to develop zero point energy to fight global warming. Oh, yeah, zero point energy as an energy source is a total butchering of the physics, as far as I can tell.
So yeah, a man on a soap-box.
He also made some suspiciously specific claims, like aliens had a federation and an agreement to not get involved. Considering the scant information he gives (and by implication what he has) that conclusion is anything but certain.
I'll take a break before I discuss the good things he said.
