Here is the GAO report released today, two years in the making, a study done for unnamed “congressional requesters.” In past years, the requesters have been listed, but in this case, they are not. This most likely reflects the sensitivity of this matter. Why so sensitive?
Because the FBI botched its investigation, never had even the shred of a case against Ivins, and this is not the first time they were called out on it. The 2011 National Academy of Science (NAS) report pointed out the same things as this GAO report: that FBI and its contractors developed methods that were not validated. They never proved that the anthrax in the letters actually grew from parent spores in Ivins’ flask, as FBI purports. This failed claim forms the linchpin of the FBI’s entire case.
Here is the 2011 WaPo editorial on the need for a comprehensive investigation, following release of the NAS report. Today’s GAO investigation did not fulfill the WaPo’s request to include an investigation of the case against Ivins himself.
Following the NAS report, in October 2011, veteran investigative reporters at McClatchey (Greg Gordon, who is amazing), PBS’ Frontline and ProPublica dug deeper into the case than anyone so far had done, and created a TV show, a huge online cache of documents on the case, and several journalistic pieces, like this one. Their work revealed new pieces of evidence that further undercut the FBI’s case, like this and this. One article explored the validity of the FBI’s scientific evidence.
UPDATE: These reporters write about the new GAO report here.
