Mary Sue was appointed by her husband as Guardian (later Controller) of the Guardian's Office (GO) in March 1966. Established in response to the battering that Scientology was receiving at the time from governments and the media, the GO was tasked with tackling any "threat of great importance" to Scientology. This work took a variety of forms, including public relations, legal actions, and the gathering of "intelligence" on perceived enemies. In the UK alone, it issued hundreds of writs against the media for publishing negative reports on Scientology. It carried out an international campaign against psychiatry, Interpol, the US Internal Revenue Service (IRS) and various other government agencies. Its eventual downfall was to result from the use of illegal methods, ordered and authorized by Mary Sue, to further its campaign.
