the Mossad." Piper also alleged that Jewish mobster Meyer Lansky and the Anti-Defamation League (ADL) were linked to the murder. The ADL responded with harsh criticisms, called the claims ridiculous, and denounced Final Judgment as antisemitic. Piper wrote articles in American Free Press which alleged that the Mossad and the FBI conspired to set up the assassination of Martin Luther King Jr. Piper claims this was motivated by fear of King's anti-Israel statements combined with his massive grassroots power. Antisemitism controversy According to his biography by American First Books, which identifies itself as promoting "white nationalism", the ADL repeatedly challenged statements made by Piper, and called him a promoter of antisemitic conspiracy theories, a Holocaust denier, and a defender of the Protocols of the Elders of Zion. The group says Piper traveled to the United Arab Emirates in 2003 to lecture on anti-Israeli and antisemitic themes. In one instance, the ADL stated that Piper had suggested that Israel was working on an "ethnic bomb" targeting only Arabs. Piper responded to increasing ADL criticism through his 2006 book The Judas Goat, accusing the ADL of using unethical infiltration and information gathering techniques, such as the use of 'agents provocateurs'. He claimed to have begun a series of events that ultimately led to the ADL Files Controversy some years later. Writing in Asia Times, researcher and journalist Keith Bettinger says that Piper's views are "characteristic of an effort by anti-Semites and white supremacists to repackage themselves as 'alternative media voices' claiming to tackle stories the mainstream media in the US won't touch". Iran Piper was invited to Iran to speak at the International Conference On Review of the Holocaust: Global Vision 2006, and personally met with Iranian president Mahmoud Ahmadinejad, a Holocaust denier, during his New York City visit to address United Nations General Assembly. His book The New Jerusalem: Zionist Power in America, was on sale at the conference. Death Piper's body was discovered on May 30 or May 31, 2015 at the Budget Saver Motel in Coeur d'Alene, Idaho. The deputy coroner's report stated that the cause of death was a "probable Myocardial Infarction, Ischemic Cardiomyopathy and Coronary Artery Disease", and listed diabetes as another significant condition. The report indicated that toxicology results were consistent with her findings and that no autopsy was conducted. The article gave Piper's age as 54.
