From its establishment in 1966 to its demise in the early 1980s, the Guardian's Office (GO) of the Church of Scientology carried out numerous covert operations and programs against a range of perceived opponents of Scientology in the United States and around the world. The GO sought to discredit, destroy or otherwise neutralize – or "depower", in Scientology jargon – any group or individual that it regarded as anti-Scientology. Instructions for such operations were distributed in the form of individually numbered "Guardian Program Orders", abbreviated as GPgmOs, which were distributed from the GO leadership to GO branches in Churches of Scientology and ultimately used to task agents.
Operation Big Mouth was a plan devised by the GO to discredit Nathan Dodell, an Assistant US Attorney who represented the government in several cases involving Scientology. Dodell was believed by the GO to be "assiduously collecting files on Scientology to show (a) harassment of the U.S. government [by Scientologists] and (b) violations of the law by Scientology." Jimmy Mulligan, an assistant to L. Ron Hubbard's wife and GO head Mary Sue Hubbard, instructed GO agents to "finally and terminatedly handle Mr. Dodell. He has been on our lines for many, many years. I would like for you to have very accurate and complete surveys done on him in D.C., and mock up and carry out some very professional, smooth, ops [operations] which will depower him fully." The Guardian's Office later concluded that it would be necessary to prove that Dodell was guilty of criminal conduct before the Church of Scientology could get him fired. GO agents repeatedly burglarized Dodell's office in the US Courthouse in Washington, D.C. and copied reams of documents about Scientology.
Operation Bulldozer Leak (July 21, 1976) was designed to "effectively spread the rumor that will lead Government, media, and individual SPs [Suppressive Persons] to conclude that LRH [L. Ron Hubbard] has no control of the C of S [the Church of Scientology] and no legal liability for church activity." Assistant Guardians in all branches of the GO were ordered "to spread the rumor" via agents working undercover, who were to approach government officials, journalists and others who had been critical of Scientology. An agent "will in several different ways mention that he has heard that LRH no longer has any control of the Church; and that an ex-Scientologist has shown some articles ... that stated that it had definitely been established in several court cases precedents that LRH had no liability for any Church activity." If contacts could not be seen personally, they were to be telephoned "and the cover story and rumor given." The agents were provided with sample scripts which included lines such as: "So while the press likes to ride with the one-leader idea so as to make press, they could not be further from the truth." The plan envisaged using Scientologists as fake authors who would interview government officials and then casually mention that they'd "heard that LRH no longer has any control of the church."
