three scientists argue that distinctive chemicals found in the dried anthrax spores — including the unexpected presence of tin — point to a high degree of manufacturing skill, contrary to federal reassurances that the attack germs were unsophisticated.
Both the chairwoman of a National Academy of Science panel that spent a year and a half reviewing the F.B.I.’s scientific work and the director of a new review by the Government Accountability Office said the paper raised important questions that should be addressed.
Or not.
But other scientists who reviewed the paper said they thought the tin might be a random contaminant, not a clue to complex processing. And the Justice Department has not altered its conclusion that the deadly letters were mailed by Dr. Ivins, an Army anthrax specialist who worked at Fort Detrick, Md., and killed himself in 2008 as prosecutors prepared to charge him.
Dean Boyd, a Justice Department spokesman, said the paper provided “no evidence whatsoever that the spores used in the mailings were produced” at a location other than Fort Detrick. He said investigators believe Dr. Ivins grew and dried the anthrax spores himself.
Or maybe so.
“It indicates a very special processing, and expertise,” said Martin E. Hugh-Jones, lead author of the paper and a world authority on anthrax at Louisiana State University. The deadly germs sent through the mail to news organizations and two United States senators, he added, were “far more sophisticated than needed.”
In addition to Dr. Hugh-Jones, the authors of the new paper are Barbara Hatch Rosenberg, a biologist, and Stuart Jacobsen, a chemist; both have speculated publicly about the case and criticized the F.B.I. for years.
In 2008, days after Dr. Ivins’s suicide, the bureau made public a sweeping but circumstantial case against him. Last year, the bureau formally closed the case, acknowledging that some scientific questions were unanswered but asserting that the evidence against Dr. Ivins was overwhelming.
Or not.
Investigators found that the microbiologist had worked unusual late-night hours in his lab in the days before each of the two known anthrax mailings in September and October 2001; that he often mailed letters and packages under assumed names; that he had a history of homicidal threats and spoke of “Crazy Bruce” as a personality that did things he later could not remember.
Dr. Ivins had hidden from family and friends an obsession with a sorority — Kappa Kappa Gamma — with an office near the Princeton, N.J., mailbox where the letters were mailed. The F.B.I. recorded Dr. Ivins’s speaking ambiguously to a friend that he did “not have any recollection” of mailing the letters, that he was “not a killer at heart” and that “I, in my right mind, wouldn’t do it.”
Yet no evidence directly tied Dr. Ivins to the crime.
Before we dive into the evidence here, let's discuss one incontrovertible fact: This case refutes the 9/11 denier article of faith that "the government" can ever act in perfect concert on anything.

My wife and I separated 4 months ago and our children, Emily and Robert, live with her but see me every weekend. I was totally devastated and confused until a old friend of mine told me about a spell caster on the internet Chief Nwaluta Mallam Zack who help people with the relationship and marriage problem by the powers of love spells, at first I doubted if such thing ever exists but decided to give it a try, when I contact him, he helped me cast a spell and within 48hours my wife came back to me and started apologizing, now she has stopped going out with men and she is with me for good and for real. Contact { nwalutaspelltemple@gmail.com } this great spell caster for your relationship or marriage problem at.
