In 1981, the "All Clear Unit" was established within the CMO, tasked with the purpose of making it "All Clear" for Hubbard to come out of hiding. One of its principal figures was David Miscavige, a 21-year-old Messenger who had worked as a cameraman for Hubbard. In May 1981, he met with Mary Sue to tell her that her position as Controller of the Guardian's Office was untenable. She reacted angrily; in a 1992 trial in Canada, Miscavige told the court that she had called him "some pretty nasty names" and threatened him with a large ashtray held close to his face, but she had eventually agreed to step down. She subsequently changed her mind, believing that she had been tricked, and wrote to her husband to complain but received no response. Numerous other Guardian's Office personnel were purged as well.
