But I was reading through Steven Jones' paper today after reading the challenge from Alex Jones' flunkies, and just about swallowed my gum when I read the provenance of Steven Jones' dust samples:
The provenience (sic) of the dust sample used in my study is from an apartment at 113 Cedar St. in New York City. This fourth-floor apartment was the residence of Janette MacKinlay and was approximately 100 meters or so from the closest Tower the South Tower.
(snip paragraph)
Janette told me that she had a sense, almost a spiritual or reverential feeling (knowing the origin of the dust) to preserve some of it, which she did, placing dust from her apartment into a plastic bag.
Yeah, I put things I have a reverential feel for into plastic bags as well. Mostly Silver Age comic books.
So now we know where Jones got his dust samples. From a gal selling 9-11 books and art. Provenience might actually be a good word for that, combining provenance and convenience.
