He is pretty cruel to trees huh he was never the same since he lost his arm in that truck accident.
The only defense for him I have is that it's very reasonable to conclude, and we have reported accounts, of real contactees being targeted by one of these specialized black projects looking to reverse engineer them (psychologically, physically implants, and any intel they can extract). That's what I would do if I was one of these black project psychopaths.
They are also known to drug you, and fuck with your mind. Missing arm? I think this guy was missing parts of his brain. I don't know if he had a real original contact with ETs.. the fake pictures, the UFO cult created.. on top of this there was more propaganda operations to place UFOs in the worst light, so a UFO cult would be ideal that later turned out to be bogus. This is excellent for ridiculing the subject so people don't look seriously into it.
There's a small chance he might be a contactee, who then was targeted, fucked with physically and mentally. But why would he then actively make the fake photos? and stupid time travel nonesense? Guys like Corey Good are used by milab for similar dis info operations, likely planting these bogus events in their memory. This is one of the saddest ufo cases I've heard, along with the idiots who committed mass suicide all at once. Morons.
I have read where they say Billy did have a real encounter but after that he had to keep the drama going and invented everything else.
