FBI Closes in on Anthrax Terrorist Prime Suspect is a Zionist by Hector Carreon La Voz de Aztlan 2/26/2002 Jewish microbiologist Dr. Philip M. Zack may be behind the deadly anthrax contaminated letters that were mailed to NBC's Tom Brokaw, Senator Tom Daschle and others, according to FBI sources. In a rapidly unravelling investigation by the FBI, it appears that the "Arab- hating-Jew" was behind a vile conspiracy to frame a colleague who was born in Egypt and who worked, along with Dr. Zack, at the U.S. Army's Medical Research Institute for Infectious Diseases in Fort Detrick, Md. La Voz de Aztlan has maintained from the beginning that the anthrax- laced letters seemed contrived and were purposely written to make them appear that they were coming from someone in the Islamic World. New information just released by the FBI confirms our suspicions. On October 9, 2001 we published "Anthrax Terrorists may be Zionists" in which we outlined the reasons for our suspicions and in addition reported on a letter we received with a yellowish powder. On October 24, 2001 we published an editorial "Anthrax Letter Messages Seem Contrived" in which we commented on our theory concerning the origin of the letters. We also published pictures of the three actual letters and envelopes. We have now compared the handwriting on these letters to the one we received and it looks suspiciously the same. We are not handwriting experts and have made the decision to publish the envelope and letter we received so that our readership can see for themselves. Our local police department never came to pick up the envelope and letter and we still have them in a double zip-lock plastic bag. The letter and envelope addressed to La Voz de Aztlan are published at http://www.aztlan.net/letterbiochem.htm The case against Dr. Phillip M. Zack began unravelling when Egyptian- born scientist Dr. Ayaad Assaad, now a U.S. citizen, was called in by the FBI for an interview on October 2, 2001. The FBI had received an unsigned letter falsely accusing Dr. Assaad of being responsible for mailing the anthrax tainted letters. The letter stated, among other things, "Dr. Assaad is a potential biological terrorist," and "I have worked with Dr. Assaad, and I heard him say that he has a vendetta against the U.S. government and that if anything happens to him, he told his sons to carry on." Rosemary A. McDermott, attorney for Dr. Assaad, stated that here is a very close connection between the person who sent that letter and the person who sent the anthrax. Ms. McDermott said "The person who wrote that letter knew intimate details of my client's life and his professional history, and about the Fort Detrick operation. I don't think that is a coincidence." The Fort Detrick biochemical research laboratory has maintained stores of weapons-grade anthrax that is commonly known as the Ames strain of Bacillus anthracis. The anonymous letter falsely accusing Dr. Assaad was was sent a little after the September 11 terrorist attacks but before anyone knew about the anthrax-laced letters. On October 5, 2001, about 10 days after the anonymous letter was mailed, Robert Stevens, Photo Editor of The Sun in Florida, became the first of five individuals to die from an anthrax infection. The racist and bigoted attacks on Dr. Ayaad Assaad by Zionist Philip Zack and others started while he worked at the Army's bioweapons lab at Fort Detrick in Maryland during the 1990's. This is when a vicious racist vendetta was launched against the scientist of Arab descent. A group of coworkers led by then Army Lt. Col. Philip Zack began a hateful campaign to harass and get Dr. Assaad fired from his duties. The Zionists apparently wanted to get rid of anyone that could uncover their sinister plans which consisted in stealing "weapons grade anthrax" and other deadly viruses used in biological weapons. The conspirators had the support of the lab's former commander. Among other things, the bigots wrote and passed around a very crude poem denigrating Arab Americans, an obscene rubber camel and constantly poked fun at Dr. Assaad's use of the English language. In 1991 Dr. Assaad discovered the eight-page poem in his mailbox. The poem was lewd and mocked Dr. Assaad. The poem also referred to the rubber camel that was passed around. It was outfitted with all manner of sexually explicit appendages. The poem in part read: ``In Assaad's honor we created this beast; it represents life lower than yeast.'' The bigots noted that the rubber camel will be given each week ``to who did the least.'' It appears that the conspirators created an extremely toxic workplace on purpose in order to take control of the laboratory. The lab became very dysfunctional and hostile to the few "good" scientists that worked there which included Dr. Assaad. Dr. Assaad said ``This person knew in advance what was going to happen and created a suitable, well-fitted scapegoat for this action. You do not need to be a Nobel laureate to put two and two together.'' Dr. Assaad said he reported everything to his supervisor, Col. David R. Franz, but that Colonel Franz ``kicked me out of his office and slammed the door in my face, because he didn't want to talk about it.'' Dr. Assaad was eventually dismissed by Colonel Franz as were two other scientists of Arab descent. The evidence against the racist Zionist bigot Dr. Philip "Mengele" Zack is very strong. Lab specimens of anthrax spores, Ebola virus and other pathogens disappeared from the Army's biological warfare research facility in the early 1990s during the very same period that the conspirators were harassing Dr. Assaad. An 1992 inquiry into the disappearance of the deadly pathogens found evidence that someone was secretly entering the laboratory late at night to conduct unauthorized research involving anthrax. A numerical counter on a piece of lab equipment had been rolled back to hide work done by the mystery researcher. A lab scientist, Dr. Mary Beth Downs, told investigators that she had come to work several times in 1992 to find that someone had been in the lab at odd hours to use the electron microscope to conduct some clandestine research. Dr. Downs reported in a memo that whoever was using the microscope was "either in a big hurry or didn't know what they were doing." Documents from the inquiry show that one unauthorized person who was observed entering the laboratory at night was Lt. Col. Philip Zack who at the time no longer worked at Fort Detrick. A surveillance camera recorded Lt. Col. Zack being let in at 8:40 P.M. on January 23, 1992, by another conspirator by the name Dr. Marian Rippy. Dr. Philip M. Zack has not been arrested. http://aztlan.net/zack.htm ------------------------------------------------------------------- September 19, 2005 Covering the Tracks of the Anthrax Attacks What, where, why -- who? by Justin Raimondo Four years ago today, letters containing anthrax were postmarked from Trenton, N.J., to five major American media outlets, including ABC News, NBC News, CBS News, the New York Post, and AMI Media, a publisher of supermarket tabloids. Thus began a series of attacks over several weeks that terrorized the nation, infected 22 people, killed five and played a key role in amplifying the post-9/11 hysteria and paranoia that took the nation on a course set for war. Three weeks after the first mailings, two letters containing highly weaponized anthrax far more deadly than the relatively crude concoction contained in the first letters showed up in the offices of two Democratic senators, Tom Daschle and Patrick Leahy. The Capitol emptied, most members of Congress fled Washington, and the country already jumpy as a result of the 9/11 terrorist attacks was practically prostrate with fear. Remember how the War Party used these attacks to stoke up sentiment for attacking Iraq? Andrew Sullivan declared: "At this point, it seems to me that a refusal to extend the war to Iraq is not even an option. We have to extend it to Iraq. It is by far the most likely source of this weapon; it is clearly willing to use such weapons in the future; and no war against terrorism of this kind can be won without dealing decisively with the Iraqi threat. We no longer have any choice in the matter. Slowly, incrementally, a Rubicon has been crossed. The terrorists have launched a biological weapon against the United States. They have therefore made biological warfare thinkable and thus repeatable. We once had a doctrine that such a Rubicon would be answered with a nuclear response. We backed down on that threat in the Gulf War but Saddam didn't dare use biological weapons then. Someone has dared to use them now. Our response must be as grave as this new threat." Nuke 'em!, said Andy without a single iota of evidence that Iraq was involved. But who needs evidence? That's soooo September 10th. Everything's changed, we were told: we don't require evidence, not anymore. All we need are vaguely portentous phrases, such as "a Rubicon has been crossed." We can make up the rest as we go along Over at the Weekly Standard, Bill Kristol was gleefully rubbing his hands together and cackling that the administration seemed finally to have signed on to the neocon prescription for taking the "war on terrorism" beyond Afghanistan, to Iraq: "Has the administration come around thanks to repeated efforts at persuasion by The Weekly Standard (and a few other hawks)? Perhaps. But a likelier explanation is that they have come to believe we'll have to take the war beyond Afghanistan to Iraq and other state sponsors of terror because they've found evidence of support by 'other states' for very recent and sinister bin Laden-related activities. "What if the anthrax cases in Florida are an act of terrorism? What if the presence of the anthrax spores there is connected to the fact that a few of the September 11 terrorists, led by Mohammed Atta, lived within a few miles? What if Atta or some other bin Laden operative had access to anthrax from the terrorist-sponsoring country that we know has a long record of developing anthrax as a biological weapon, Iraq?" Unlike the more emotive Sullivan for whom evidence of an Iraq connection would only be an unnecessary drag on his breathy imprecations the cool-headed Kristol came up with a scenario meant to convince the reader that such a connection was at least possible. It involved the now famous and decidedlydisproved meeting between Mohammed Atta and an alleged Iraqi intelligence agent in Prague. Although the Czech police denied it, the myth persisted, and grew: not only did Atta plan the 9/11 terrorist attacks in collaboration with Iraqi intelligence on his trip to Prague, he also according to Kristol and James "World War IV" Woolsey hatched the anthrax plot. However, given that this mythical meeting, conducted in the course of six busy hours, was alleged to have taken place at the Prague airport, and was conducted within range of security cameras, one wonders if passing vials of anthrax under such circumstances might have proven somewhat problematic. Oh well, the War Party didn't need especially logical arguments in stoking the fires of American rage: the smoke had yet to lift from downtown Manhattan, and the victims of the Twin Towers and Pentagon attacks were still being counted. As anthrax panic gripped the nation, the White House was preparing to extend the war to "other countries" a prospect Kristol & Co. found thrilling. If the administration wouldn't bow to the bellicose blandishments of the Weekly Standard, then perhaps they would bend before the amplified fear of terrorism raised by the anthrax attacks. And so they did. In retrospect, outrage and fear generated by the anthrax attacks were essential elements of the propaganda campaign designed to link Iraq to terrorism in the U.S. and drag us into war. The attacks were so propitious in this regard that one might be forgiven for wondering if the perpetrators had this as their intention. Certainly they took great pains to convey the impression that the postal pestilence was authored by angry Arabs of one sort or another. Also, in retrospect, the investigation into the anthrax mystery seems remarkably botched, a kind of pre-Katrina premonition of a dangerous even criminal incompetence. The authorities quickly seized on one Steven J. Hatfill, a government scientist and a somewhat hapless figure, against whom not a single shred of solid evidence could be marshaled. Yet Hatfill was branded a "person of interest" and relentlessly harassed by government agents, who in collaboration with a certainNew York Times columnist destroyed his reputation. U.S. government agents followed him everywhere, made his life a misery, and refuse to this day to either apologize or offer some small compensation to a man whose life they have ruined. It is interesting that the U.S. government was all too eager to follow the path suggested by journalists such as Nicholas Kristof, one of Hatfill's earliest and most relentless nemeses, while studiously ignoring the clues provided by others. The Hartford Courant ran a series of articles by Dave Altimari, Lynne Tuohy, and Jack Dolan that not only pointed in the direction of the possible perpetrators, but named names and implied a political-ideological motive behind the crime. The anthrax strain has been positively identified as being of the Ames variety, of the sort stored at USAMRIID, the U.S. government biological weapons facility at Fort Detrick, Md., and a few other such labs. Soon after the anthrax attacks, the Courantexposed the weird problems besetting the Ft. Detrick facility, which had apparently been missing large quantities of biological toxins, including not only anthrax but also hanta virus, Ebola virus, and other lethal pathogens. These mysterious disappearances apparently occurred: "During a turbulent period of labor complaints and recriminations among rival scientists there, documents from an internal Army inquiry show. The 1992 inquiry also found evidence that someone was secretly entering a lab late at night to conduct unauthorized research, apparently involving anthrax. A numerical counter on a piece of lab equipment had been rolled back to hide work done by the mystery researcher, who left the misspelled label 'antrax' in the machine's electronic memory, according to the documents obtained by The Courant." This "mystery researcher" may have been someone at the very center of that "turbulent period," one Philip Zack. Zack and a group of personnel at Ft. Detrick had been systematically harassing an Egyptian co-worker, Dr. Ayaad Assaad. The Courant reports: "Documents from the inquiry show that one unauthorized person who was observed entering the lab building at night was Langford's predecessor, Lt. Col. Philip Zack, who at the time no longer worked at Fort Detrick. A surveillance camera recorded Zack being let in at 8:40 p.m. on Jan. 23, 1992, apparently by Dr. Marian Rippy, a lab pathologist and close friend of Zack's, according to a report filed by a security guard." The harassment of Assaad, detailed here, took on bizarrely juvenile forms: an obscene poem, a rubber camel delivered to his mailbox, a constant stream of racist anti-Arab remarks such as one might find posted these days on Little Green Footballs. Court documents reveal a harrowing experience of cruel and relentless persecution carried out by a small clique, including Zack, who called themselves the "camel club." While the anthrax letters received enormous publicity, one mailed missive that might provide a key clue to the identity of the perpetrators has received very little: an anonymous letter, sent in late September before the anthrax drama unfolded, to the military police at the Marine base in Quantico, Va., accused Dr. Assaad of being behind a terrorist plot to unleash biological horrors in American cities. The author revealed a detailed knowledge of Dr. Assaad's career at USAMRIID and claimed to have formerly worked with him. Assaad was interrogated by the FBI on Oct. 3, then let go after the letter was determined to be a hoax. When the effects of the anthrax attacks began to make themselves known, the full horror of what had happened began to dawn on Assaad but not, apparently, on the authorities. Says Assaad: "My theory is, whoever this person is knew in advance what was going to happen (and created) a suitable, well-fitted scapegoat for this action." The odd timing of the letter sent after the anthrax letters were mailed, but before their deadly contents were known certainly seems to point in this direction. The Courant reports FBI spokesman Chris Murray saying "the FBI is not tracking the source of the anonymous letter, despite its curious timing, coming a matter of days before the existence of anthrax-laced mail became known." Instead of following the trail of this important clue, investigators went off on a tangent with the Hatfill angle, which proved [.pdf] to be a dead end. An Egyptian scientist, albeit one who is an American citizen and had lived in this country for quite some time, had been set up as the scapegoat for the crime before knowledge of the mailed anthrax was generally known. This same scientist had been the object of a hate campaign generated by virulently anti-Arab co-workers at Ft. Detrick, at least one of whom was videotaped surreptitiously entering the lab at night (after he had been dismissed from his position and was not authorized to enter in any event). Whoever wrote the poison pen letter denouncing Dr. Assaad as a potential terrorist in all likelihood knows something about the origins of the anthrax attack. In this context, the crudeness of the messages accompanying the anthrax "death to America" and "death to Israel" seems like an obvious effort to divert attention away from the real authors of a crime that goes unsolved to this day. Just as the Bush administration was looking for an excuse any excuse to take out after Iraq, the anthrax horror reared its head and silenced any remaining opposition to the war plans of this administration, at least momentarily. It all seems like such a terribly convenient coincidence. In retrospect, it was as much a part of the vortex of fearmongering that sucked us into war as tales of Iraqi WMD palmed off by Ahmed Chalabi's "heroes in error" and the extravagant effusions of Dick Cheney and Condoleezza Rice. No, I am not suggesting that the U.S. government or the Bush administration carried out these attacks: yet whoever did surely had in mind making it easier for the War Party to unleash mass death and destruction in the Middle East, a veritable wave of hate that would carry us to Baghdad and beyond. Why isn't Congress investigating this? Where is the probe into the "intelligence failure" that managed to target and destroy an innocent person while pulling investigators away from evidence pointing in a more plausible direction? Whoever pulled off the anthrax attacks is still out there, waiting for the right moment to strike. This is a case that must be solved because there's more where that came from. http://www.antiwar.com/justin/ [Note: Justin Raimondo has been in the forefront of exposing the hate-motivated injustices that Drs. Assaad and Hatfill have faced.

The 1992 inquiry also found evidence that someone was secretly entering a lab late at night to conduct unauthorized research, apparently involving anthrax. A numerical counter on a piece of lab equipment had been rolled back to hide work done by the mystery researcher, who left the misspelled label "antrax" in the machine's electronic memory, according to the documents obtained by The Courant. Experts disagree on whether the lost specimens pose a danger. An Army spokesperson said they do not because they would have been effectively killed by chemicals in preparation for microscopic study. A prominent molecular biologist said, however, that resilient anthrax spores could possibly be retrieved from a treated specimen. In addition, a scientist who once worked at the Army facility said that because of poor inventory controls, it is possible some of the specimens disappeared while still viable, before being treated. Not in dispute is what the incidents say about disorganization and lack of security in some quarters of the U.S. Army Medical Research Institute of Infectious Diseases - known as USAMRIID - at Fort Detrick, Md., in the 1990s. Fort Detrick is believed to be the original source of the Ames strain of anthrax used in the mail attacks last fall, and investigators have questioned people there and at a handful of other government labs and contractors. It is unclear whether Ames was among the strains of anthrax in the 27 sets of specimens reported missing at Fort Detrick after an inventory in 1992. The Army spokesperson, Caree Vander-Linden, said that at least some of the lost anthrax was not Ames. But a former lab technician who worked with some of the anthrax that was later reported missing said all he ever handled was the Ames strain. Meanwhile, one of the 27 sets of specimens has been found and is still in the lab; an Army spokesperson said it may have been in use when the inventory was taken. The fate of the rest, some containing samples no larger than a pencil point, remains unclear. In addition to anthrax and Ebola, the specimens included hanta virus, simian AIDS virus and two that were labeled "unknown" - an Army euphemism for classified research whose subject was secret. A former commander of the lab said in an interview he did not believe any of the missing specimens were ever found. Vander-Linden said last week that in addition to the one complete specimen set, some samples from several others were later located, but she could not provide a fuller accounting because of incomplete records regarding the disposal of specimens. "In January of 2002, it's hard to say how many of those were missing in February of 1991," said Vander-Linden, adding that it's likely some were simply thrown out with the trash. Discoveries of lost specimens and unauthorized research coincided with an Army inquiry into allegations of "improper conduct" at Fort Detrick's experimental pathology branch in 1992. The inquiry did not substantiate the specific charges of mismanagement by a handful of officers. But a review of hundreds of pages of interview transcripts, signed statements and internal memos related to the inquiry portrays a climate charged with bitter personal rivalries over credit for research, as well as allegations of sexual and ethnic harassment. The recriminations and unhappiness ultimately became a factor in the departures of at least five frustrated Fort Detrick scientists. In interviews with The Courant last month, two of the former scientists said that as recently as 1997, when they left, controls at Fort Detrick were so lax it wouldn't have been hard for someone with security clearance for its handful of labs to smuggle out biological specimens. Lost Samples The 27 specimens were reported missing in February 1992, after a new officer, Lt. Col. Michael Langford, took command of what was viewed by Fort Detrick brass as a dysfunctional pathology lab. Langford, who no longer works at Fort Detrick, said he ordered an inventory after he recognized there was "little or no organization" and "little or no accountability" in the lab. "I knew we had to basically tighten up what I thought was a very lax and unorganized system," he said in an interview last week. A factor in Langford's decision to order an inventory was his suspicion - never proven - that someone in the lab had been tampering with records of specimens to conceal unauthorized research. As he explained later to Army investigators, he asked a lab technician, Charles Brown, to "make a list of everything that was missing." "It turned out that there was quite a bit of stuff that was unaccounted for, which only verifies that there needs to be some kind of accountability down there," Langford told investigators, according to a transcript of his April 1992 interview. Brown - whose inventory was limited to specimens logged into the lab during the 1991 calendar year - detailed his findings in a two-page memo to Langford, in which he lamented the loss of the items "due to their immediate and future value to the pathology division and USAMRIID." Many of the specimens were tiny samples of tissue taken from the dead bodies of lab animals infected with deadly diseases during vaccine research. Standard procedure for the pathology lab would be to soak the samples in a formaldehyde-like fixative and embed them in a hard resin or paraffin, in preparation for study under an electron microscope. Some samples, particularly viruses, are also irradiated with gamma rays before they are handled by the pathology lab. Whether all of the lost samples went through this treatment process is unclear. Vander-Linden said the samples had to have been rendered inert if they were being worked on in the pathology lab. But Dr. Ayaad Assaad, a former Fort Detrick scientist who had extensive dealings with the lab, said that because some samples were received at the lab while still alive - with the expectation they would be treated before being worked on - it is possible some became missing before treatment. A phony "log slip" could then have been entered into the lab computer, making it appear they had been processed and logged. In fact, Army investigators appear to have wondered if some of the anthrax specimens reported missing had ever really been logged in. When an investigator produced a log slip and asked Langford if "these exist or [are they] just made up on a data entry form," Langford replied that he didn't know. Assuming a specimen was chemically treated and embedded for microscopic study, Vander-Linden and several scientists interviewed said it would be impossible to recover a viable pathogen from them. Brown, who did the inventory for Langford and has since left Fort Detrick, said in an interview that the specimens he worked on in the lab "were completely inert." "You could spread them on a sandwich," he said. But Dr. Barbara Hatch Rosenberg, a molecular biologist at the State University of New York who is investigating the recent anthrax attacks for the Federation of American Scientists, said she would not rule out the possibility that anthrax in spore form could survive the chemical-fixative process. "You'd have to grind it up and hope that some of the spores survived," Rosenberg said. "It would be a mess. "It seems to me that it would be an unnecessarily difficult task. Anybody who had access to those labs could probably get something more useful." Rosenberg's analysis of the anthrax attacks, which has been widely reported, concludes that the culprit is probably a government insider, possibly someone from Fort Detrick. The Army facility manufactured anthrax before biological weapons were banned in 1969, and it has experimented with the Ames strain for defensive research since the early 1980s. Vander-Linden said that one of the two sets of anthrax specimens listed as missing at Fort Detrick was the Vollum strain, which was used in the early days of the U.S. biological weapons program. It was not clear what the type of anthrax in the other missing specimen was. Eric Oldenberg, a soldier and pathology lab technician who left Fort Detrick and is now a police detective in Phoenix, said in an interview that Ames was the only anthrax strain he worked with in the lab. Late-Night Research More troubling to Langford than the missing specimens was what investigators called "surreptitious" work being done in the pathology lab late at night and on weekends. Dr. Mary Beth Downs told investigators that she had come to work several times in January and February of 1992 to find that someone had been in the lab at odd hours, clumsily using the sophisticated electron microscope to conduct some kind of off-the-books research. After one weekend in February, Downs discovered that someone had been in the lab using the microscope to take photos of slides, and apparently had forgotten to reset a feature on the microscope that imprints each photo with a label. After taking a few pictures of her own slides that morning, Downs was surprised to see "Antrax 005" emblazoned on her negatives. Downs also noted that an automatic counter on the camera, like an odometer on a car, had been rolled back to hide the fact that pictures had been taken over the weekend. She wrote of her findings in a memo to Langford, noting that whoever was using the microscope was "either in a big hurry or didn't know what they were doing." It is unclear if the Army ever got to the bottom of the incident, and some lab insiders believed concerns about it were overblown. Brown said many Army officers did not understand the scientific process, which he said doesn't always follow a 9-to-5 schedule. "People all over the base knew that they could come in at anytime and get on the microscope," Brown said. "If you had security clearance, the guard isn't going to ask you if you are qualified to use the equipment. I'm sure people used it often without our knowledge." Documents from the inquiry show that one unauthorized person who was observed entering the lab building at night was Langford's predecessor, Lt. Col. Philip Zack, who at the time no longer worked at Fort Detrick. A surveillance camera recorded Zack being let in at 8:40 p.m. on Jan. 23, 1992, apparently by Dr. Marian Rippy, a lab pathologist and close friend of Zack's, according to a report filed by a security guard. Zack could not be reached for comment. In an interview this week, Rippy said that she doesn't remember letting Zack in, but that he occasionally stopped by after he was transferred off the base. "After he left, he had no [authorized] access to the building. Other people let him in," she said. "He knew a lot of people there and he was still part of the military. I can tell you, there was no suspicious stuff going on there with specimens." Zack left Fort Detrick in December 1991, after a controversy over allegations of unprofessional behavior by Zack, Rippy, Brown and others who worked in the pathology division. They had formed a clique that was accused of harassing the Egyptian-born Assaad, who later sued the Army, claiming discrimination. Assaad said he had believed the harassment was behind him until last October, until after the Sept. 11 terrorist attacks. He said that is when the FBI contacted him, saying someone had mailed an anonymous letter - a few days before the existence of anthrax-laced mail became known - naming Assaad as a potential bioterrorist. FBI agents decided the note was a hoax after interviewing Assaad. But Assaad said he believes the note's timing makes the author a suspect in the anthrax attacks, and he is convinced that details of his work contained in the letter mean the author must be a former Fort Detrick colleague. Brown said that he doesn't know who sent the letter, but that Assaad's nationality and expertise in biological agents made him an obvious subject of concern after Sept. 11.
