* GAO: Doesn’t the FBI’s photocopy toner report EXCLUDE the make and model of photocopier used at USAMRIID but INCLUDE the make and model used in the Maryland KINKOS so often used by the hijackers in August and September 2001?

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

I raised the issue of photocopy toner with Dr. Majidi. He says the key is the genetics inquiry and the 4 morphs. But the morphs only narrowed things from 700-1000 to 200-300. And that was just at USAMRIID! A smidgeon from USAMRIID or other places then could be taken anywhere.
Indeed, even Vahid’s application of the 4 morphs issue was totally botched — and that is apparent from the face of the FBI’s August 2008 press conferences which talked about excluding the 100 with access at Building 1425. The fact that Vahid told US Attorney Taylor that only the 100 in Building 1425 needed to be excluded, without more, demolishes an Ivins Theory. (As one example, Vahid excluded Dr. Hatfill based on his confusion that the genetically matching Ames was not also in Building 1412.) See, e.g., Heine interviews and testimony.
Vahid and AUSA Lieber and Agent Lawrence Alexander (fresh off working undercover street drugs and gangs) took the scientific and factual issues and distorted and miscast the data to fit their theory.
At the heart of Lawrence and Rachel’s confusion on the hours was their failure to realize that a two-person rule was implemented in January 2002. Thus you would have expected the hours to stop at the end of December 2001 — as they did and Agent Alexander’s own powerpoint to Rachel showed.
At the very least, they could have ensured that all traditional forensic reports were produced — such as the examination of the photocopy toner and testing of the papers taken from Ivins’ home.
Depending on what the examination of the toner shows, they then can explain that Dr. Ivins never xeroxed at the same machine for any other purpose.
Their Ivins Theory, at the end of the day, was based on the reports by some who found Ivins creepy. They were working in what Mrs. Clinton might call an “evidence free zone.”
One of the therapists they relied upon wrote a 2009 book explaining that she got her instructions at night from an alien who had implanted a microchip in her butt. She thought murderous astral entities were attached to the clients in her new parti-time counseling gig. She annotated the psychiatric file and then that file was given to the second therapist who sought a restraining order in light of Ivins’ rage.
In any event: You simply don’t withhold forensic reports … you especially don’t withhold forensic reports and then claim that they were produced.
Withholding data in the scientific realm constitutes misconduct.
Withholding evidence in the legal realm constitutes misconduct.
The misconduct, which will be presumed an oversight, can be cured by producing the documents now.
The problem is that AUSA Lieber assured me that I would never get such documents under FOIA — all that was ever going to be produced had been produced.
And submitting FOIAs to the FBI on Amerithrax has indeed been a black sinkhole.

The printed document was first screened using a portable-X-ray fluorescence (XRF) probe. If the results were not conclusive, a laser microprobe was then deployed. The laser probe was based on a two-pulse scheme: the first laser pulse ablated a thin layer of the printed ink; the second laser pulse at 193 nm induced multianalytes in the desorbed ink to fluoresce. We analyzed four brands of black toners. The toners were printed on paper in the form of patches or letters or overprinted on another ink. The XRF probe could sort the four brands if the printed letters were larger than font 20. It could not tell the printing sequence in the case of overprints. The laser probe was more discriminatory; it could sort the toner brands and reveal the overprint sequence regardless of font size while the sampled area was not visibly different from neighboring areas even under the microscope. In terms of general analytical performance, the laser probe featured tens of micrometer lateral resolution and tens to hundreds of nm depth resolution and atto-mole mass detection limits. It could handle samples of arbitrary size and shape and was air compatible, and no sample pretreatment was necessary. It will prove useful whenever high-resolution and high sensitivity 3D elemental mapping is required. [ABSTRACT FROM AUTHOR].

.Abstract:The Metropolitan Police Forensic Science Laboratory in London, U.K., has developed a method that can determine the source of laser-printed documents from microscopic marks on the paper. Laser printers transfer toner onto the paper using a rotating light-sensitive drum. Any defect in the photosensitive coating on the drum’s surface will lead to tiny specks appearing on the documents it prints. These specks can link the document to the printer it was produced on. This identification technique is expected to be used shortly by forensic scientists in British courts..ISSN:02624079

Abstract

abstract
A photocopied document can expose the photocopier characteristics to identify the source photocopier, so how to extract the optimal intrinsic features is critical for photocopier forensics. In this paper, a photocopier forensics method based on the texture features analysis for arbitrary characters is proposed and the features are considered as the intrinsic features. Firstly, an image preprocessing process is practiced to get individual character images. Secondly, three sets of features are extracted from each individual character image, including the gray level features, the gradient differential matrix (GDM) features and the gray level gradient co-occurrence matrix (GLGCM) features. Last, each individual character in a document is classified using a Fisher classifier and a majority vote is performed on the character classification results to identify the source photocopier. Experimental results on seven photocopiers prove the effectiveness of our proposed method and an average character classification accuracy of 88.47% can be achieved. © (2013) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).

GAO, it is important that the forensic tests regarding the photocopy toner be obtained and disclosed.

“FBI Whistleblower Whitehurst Source of Washington Post Article
Today, the Washington Post ran a front-page story on the Justice Department keeping forensic flaws from the defendant and defense attorneys. The NWC and FBI whistleblower Dr. Frederic Whitehurst spent years on a Freedom of Information Act (FOIA) case that directly lead to today’s Washington Post story.
Dr. Whitehurst, NWC’s Board Member and Director of the NWC’s Forensic Justice Department, blew the whistle on the misconduct at the FBI crime lab in the early 1990s. Dr. Whitehurst vowed to find all the defendants harmed by the FBI’s misconduct and established the NWC Forensic Justice Project.
Without Dr. Whitehurst’s continued perseverance through his oversight activities in the past 10 years at the NWC, seeking information about the DOJ’s review directly resulting from his whistleblower allegations, this misconduct never would have come to light.
More information COMING SOON!”

Under a 2000 contract, Xerox was Kinko’s primary supplier of color and monocrhome photocopiers for 1,000 Kinko’s locations across the United States and Canada.
Doesn’t the mass spec on the photocopy toner done in 2001 show that a Xerox brand photocopier was used? (See December 2001 media reports about FBI visits to KINKOS).
For more than 30 years Xerox and Kinko’s have forged a partnership built on common values including quality and continuous innovation,” said Mike MacDonald, president, Xerox North American Solutions Group. “Installing the latest Xerox technology in Kinko’s stores across the U.S. and Canada solidifies Kinko’s leadership in the document services industry and underscores our resolve to achieve a dramatic corporate turnaround by continuing to put customers first.”
