One of the reason I used Blevins as an example is due to evidence. Robert states a lot of things but fails to show any actual proof backing it up. nobody has come forward, none of the actual testimony has ever been shown. it all comes from one person telling the story. even the PDF is questionable, he states he hand delivered it, but also states it was sent? and by the way, the FBI doesn't look at potential evidence in a "cursory" fashion.. either it's valuable, or it's not.
Gunthers book seems to follow a similar trail. it's not that he held back showing what someone has claimed, it's just the claims can't be proven. "Clara" could be nobody, or only exist on paper. as Ralph stated (show me the money) should have been an easy task for this person. then you have the factual error's being made by someone who was getting first hand information, how could this happen? then you have the possibility that Clara was someone like Bob Knoss. he actually believed what he was saying and went to great lengths to try and explain his story, but stated things in a way that they couldn't be researched. Knoss made it into a book as well, Gray's book. he ended up taking Gray on a wild goose chase proving nothing...Clara could of been lied to as well....
I've seen a lot of wild things happen with this case. a lot of it surrounds people with suspects, not all of them but a majority tell some wild things. I'm not saying this book is all fiction, but I would need a lot more proof before I would give it any merit. has anyone really looked into how chemical plants function? do we have evidence proving the tie is linked to chemical plants? it appears to be more into the CRT realm vs other leads...this could also end up being wrong as well. it's to early to conclude anything.
My personal opinion is the book has a lot of problems for being known to have personal knowledge from the criminal himself. the lack of attention by the FBI is taken into consideration as well. the book was discussed on Dropzone years ago, but I didn't read everything from it, but it appears it didn't go over well there either.
