In addition to violating and abusing its own members civil rights, the [Scientology] organization over the years with its "Fair Game" doctrine has harassed and abused those persons not in the Church whom it perceives as enemies. The organization clearly is schizophrenic and paranoid, and this bizarre combination seems to be a reflection of its founder LRH. The evidence portrays a man who has been virtually a pathological liar when it comes to his history, background, and achievements. The writings and documents in evidence additionally reflect his egoism, greed, avarice, lust for power, and vindictiveness and aggressiveness against persons perceived by him to be disloyal or hostile. At the same time it appears that he is charismatic and highly capable of motivating, organizing, controlling, manipulating, and inspiring his adherents.
