He used earlier forum name variations elsewhere to threaten people using "dark crystal energy forces" on social media.
Both his egos here did seem to have that lashing-out quality. Unlike our other resident spiritualists, he claimed spirits could cause people harm and did so regularly. The story he tripped up on during his previous visit argued that he was being vexed by an evil spirit at the same time every day.
And no, I don't think he has the slightest clue what evidence actually is -- in a legal, scientific, or any practical sense.
The contents of a book would hardly be legal evidence of whatever's asserted in the book.
Yay, here's the part where Loss Leader bludgeons me with the dark crystal magic of Rule 803. Too little caffeine in my system yet to have much to say, thankfully.
No, I highly doubt the kinds of books I'm sure he was prepared to cite would not be considered evidence of the fact of matters reported in them or the strength of the conclusions of their authors. Properly certified by rule, they would be, as you say, evidence only that the book contains words.
It might be evidence that the book was consulted by some proposed expert on some matter.
Alluding to Rule 803(6)(d), I have a custodian of records that collects records kept for some of our daily activity on certain contracts. She requires us to keep the records in a certain form and to surrender them to her according to a curation and retention policy. That is still only evidence in a limited sense. It believe it would be material in such actions as for patent infringement. Not really the sort of book Cris was talking about.
But more to the point, there are references common in every field that might qualify under section 17 of the rule. Say, the Schaum's handbook, if you deal regularly with mathematics. But even then you might need an expert witness, depending on how you wanted to use the information as evidence. In any case, not the kind of book likely referred to.
Someone did ask for evidence of the daughter's existence and, if I recall correctly, of her death. Sections 9 and 11 would seem to apply, and the poster could have presented evidence from, say, a parish register and it would seem to me to qualify as an exception to the hearsay rule. But I don't think that was the kind of book he had in mind.
Section 13 refers to inscriptions on a ring. I assume that would just be Tolkien evidence.
I guess if one side puts up a purported expert in Artificial Intelligence and that person's sole training in the field came from reading William Gibson novels, you could get it in to impeach the witness. Otherwise, I'm stumped.
Yeah, I guess you could delve into the contents of the book, but it would seem more straightforward to qualify a computer science expert as an adverse witness to testify that Gibson novels do not create a proper foundation of understanding. Am I on the right track? They certainly don't qualify as learned treatises, if that matters.
