This paper analyzed the issue of ”passing laws governing concealing campus sexual assaults” through the lens of ”passive evil.” It emphasized that the liabilities that educators incur when they ignore or conceal campus sexual assaults has been expanded from moral responsibility to more severe punishments including permanent disqualification. Therefore this issue has already become a serious accusation on educators' passivity rather than just a groundless ”false issue.” By incorporating relevant literature, regulations and orders, practical cases, media reports, and focus group interviews into a coherent framework, this paper revealed that the causes for concealing campus sexual assault for educators consist of ”belief and value from subjective construction,” ”private calculations for personal interest,” ”concern about persecution after the event,” ”selfishness from personal affection,” ”procrastination in systematic operation,” ”social dynamic of group members,” and ”self-expectation for organizational interest.” This paper concludes by discussing the implications of passing such laws in educational administration and proposing some suggestions.
