CASE CLOSED … what really happened in the 2001 anthrax attacks?

    Al-Qaeda leader Zawahiri is said to have ordered terrorist attack

    By Ellen Nakashima and Anne Gearan, Published: August 5

    Al-Qaeda leader Ayman al-Zawahiri ordered the head of the terrorist group’s Yemen affiliate to carry out an attack, according to intercepted communications that have led to the closure of U.S. embassies and a global travel alert, said a person briefed on the case.

    In one communication, Zawahiri, who succeeded Osama bin Laden, gave “clear orders” to Nasir al-Wuhayshi, the founder of al-Qaeda in the Arabian Peninsula, to undertake an attack, the source said. McClatchy newspapers first reported the exchange on Sunday.

    The electronic communication between the two terror leaders reportedly indicated that the attack was imminent but did not reveal the specific target.

    Though it is no fault of the FBI that there was not an existing validation of sampling methods, it is critical to understand that at the overseas location, not only was there the background problem of lack of validation discussed in the recent GAO report on the narrow issue, but with the clandestine labs the plan was always for the lab to be wiped down with insecticide — the walls were to be painted precisely to permit more effective decontamination.

    In science, as in legal advocacy, how an issue is framed is critical.

    Where is decontamination discussed in the FBI testing of the overseas labs?

    The FBI could have learned the insecticide used in interrogation of Sufaat’s assistants and then tested for the presence of the insecticide or other decontamination agent.

    “Collectively, our studies describe correlation be- tween B. anthracis cell surface hydrophobicity and re- duced sample recovery from environmental surfaces.”

    Effects of Bacillus anthracis hydrophobicity and induction of host cell death on sample collection from environmental surfaces.

    The objective of this study is to determine whether DNA signature recovery of Bacillus anthracis strains from different environmental substrates correlates with pathogen cell surface hydrophobicity and induction of host cell death. We compared recovery of DNA signatures from a panel of B.anthracis strains collected from two environmental substrates, non-porous surfaces and soil, using real-time qPCR. We further assessed both cell surface hydrophobicity of the B. anthracis strains by contact angle measurements and host cell viability in response to B. anthracis infection in a mouse macrophage cell model system. Our studies demonstrated correlation between reduced B. anthracis sample recovery from environmental substrates and increased cell surface hydrophobicity. Surprisingly, the most hydrophilic strain, K4596, which exhibited the highest level of recovery from the environmental surfaces, induced the highest level of host cell cytotoxicity compared to more hydrophobic B. anthracis strains in the panel. Our results suggest that cell surface hydrophobicity may play a leading role in mediating pathogen adherence to environmental surfaces. These findings can contribute to the optimization of pathogen detection efforts by understanding how bacterial parameters such as hydrophobicity and induction of host cell death affect bacterial adherence to environmental surfaces.

    In a June 1999 memo, however, he talked about building labs (with one being closed every three months so it can be moved and replaced by another), and planned to have them covered with oil paint so they might be cleaned with insecticides. Why the FBI would not take into account that the labs had been decontaminated is an issue that the GAO will need to take up with the FBI scientists. Amerithrax represents the greatest ntelligence analysis failure in the history of the United States — and that failure was led by the FBI and CIA scientists whose job it was to integrate the scientific and investigative information.

    Dr. Ayman’s planning with Atef involved wiping down the lap with insecticide as it was moved. Dr. Ayman in his planning notes, I think (if I am recalling correctly) planned on moving the lab every 3 months. Yazid, what did you folks use? Paraformaldehyde?

    Did the US FBI testify for insecticide as they got the positive (but inconsistent) findings for the anthrax you had been using?

    Well, they withheld the documents from the NAS for years and so it never could be meaningfully examined.

    They flatter themselves to think that their analysis or relations with foreign governments needs to be classified.

    And if it required clearance, then clearance should have been arranged at the outset.
