Protests were organized outside the courthouse in Canada and near Leuchter's home in
Malden, Massachusetts. Despite the bad publicity, he remained active as a capital punishment consultant until 1990, when his lack of qualifications to practice was exposed. In the late 1980s, following the
Ernst Zündel trial, he was featured in both
The Atlantic Monthly and
Primetime Live in items on capital punishment, neither of which mentioned his association with Zündel. Also following his involvement in the Zündel trial, Leuchter began lecturing to
Holocaust denial groups, such as the
Institute for Historical Review (IHR), about his research and continued belief in the conclusions he testified to in the trial. In a speech to the Eleventh IHR Conference in October 1992, he said: In this case, it is myself that I
post mortem—and the cadaver isn't dead! Much to the dismay of my executioners, the execution was so badly botched that I am able to stand here before you to speak the truth, and to tell the world that it is not myself, but the Holocaust story that is dead. I repeat for the record: I was condemned for maintaining that there were no execution gas chambers as Auschwitz, Birkenau,
Majdanek,
Dachau,
Mauthausen, or
Hartheim Castle. There's no proof for the charge, only innuendo, lies, and half-truths.
Robert Faurisson, Ernst Zundel and others said this first. They, too, live as victims of botched executions, but nevertheless free to speak the truth in a strong and growing voice that repeats: No gas chambers, no gas chambers, no damn gas chambers!Because I was somewhat naïve at the time, I was not aware that by so testifying I was offending the organized world
Jewish community. By providing final, definitive proof that there were no execution gas chambers utilized for
genocidal purposes by the
Germans at these wartime camps, I established the simple fact that the Holocaust story is not true. What I did not know was that anyone expressing such beliefs is guilty of a capital crime: that of thinking and telling the unspeakable truth about the greatest lie of the age.I would have to pay for this crime. While I innocently told the truth in
Toronto, plans were made, and subsequently implemented, for a major effort to destroy me. If I could be destroyed and discredited—so the reasoning went—no one would accept my professional findings, no matter how truthful. When he claimed that the Massachusetts Attorney General determined that the sale of the offered equipment was not, in fact, illegal, states started denying his contracts on the basis of his lack of qualifications. His wife divorced him in this same period. He had been banned from entering the country by the
Home Office, thus his entry and presence there were illegal. Leuchter claimed that United States consulate personnel effectively refused him aid. He had been interrupted while giving an invited speech at
David Irving's instigation; his talk followed immediately one by
Robert Faurisson. Leuchter has blamed criticism of his work on an "international cabal ... those who have unjustly attacked me and violated my rights ... the
Klarsfelds, Shapiros, and Kahns of the world". According to the
Institute for Historical Review, Leuchter subsequently took employment as a
telemarketer. According to
The New York Times, before selling execution equipment, Leuchter was a dealer in military surveillance equipment. On October 24, 1990,
The New York Times described him as "self-proclaimed execution expert and manufacturer of death machinery." It quoted Edward A. Brunner, chairman of the
anesthesia department at
Northwestern University Medical School, as saying Leuchter's lethal injection system would indeed
paralyze a condemned criminal with
Pavulon, but that far from being humane, the paralysis would merely stop the prisoner from screaming at the "extreme pain in the form of a severe burning sensation" caused by the
potassium chloride injection. Potassium chloride is commonly used in judicial execution through lethal injection. Leuchter's electric chair design was used by the state of Tennessee to execute
Daryl Holton in 2007 and
Edmund Zagorski in 2018.
Allegations of dishonest court appearances In 1990
Newsweek reported
Alabama assistant attorney general
Ed Carnes having called Leuchter's views on the gas chamber "unorthodox", and alleging that "Leuchter was running a death row shakedown scheme: if a state didn't purchase Leuchter's services, he would testify at the last minute for the condemned man that the state's death chamber might malfunction." The
Associated Press quoted Carnes as claiming that Leuchter made "money on both sides of the fence". In his memorandum to death penalty states, Carnes observed that in Florida and Virginia the federal courts had rejected Leuchter's testimony as unreliable. The court in
Florida had found that Leuchter had "misquoted the statements" contained in an important
affidavit and had "inaccurately surmised" a crucial premise of his conclusion. In
Virginia, Leuchter provided a death row inmate's attorney with an affidavit claiming the
electric chair would fail. The Virginia court decided the credibility of Leuchter's affidavit was limited because Leuchter was "the refused contractor who bid to replace the electrodes in the Virginia chair".
Charges of practicing without a license In 1991 Leuchter faced charges of practicing engineering without a license issued by the Board of Registration of Professional Engineers and of Land Surveyors, which
regulates professional engineers, a violation of Massachusetts law. He settled with prosecutors by serving two years of probation and agreeing to stop disseminating documents in which he presented himself as an engineer, including the Leuchter report. In a speech given over a year later, Leuchter claimed that: a spurious criminal complaint was filed against me in the Massachusetts court system with the intent of destroying my reputation by putting me in prison for three months.In point of fact, a license is not required in Massachusetts, or any other state, unless the engineer is involved in construction of buildings, and is certifying compliance with specifications. There is also a statutory exemption for engineers who do not deal with the general public.As confirmation of the spurious nature of this charge, it should be pointed out there are more than fifty thousand practicing engineers in Massachusetts, of whom only five thousand are licensed. Although the state's licensing law has been in effect since 1940, there has been no record of any prosecution for this offense. Leuchter attributed the actions of the regulatory board against him to pressure from Jewish groups. ==Documentary==
