A significant percentage of sexual assault cases never get beyond this stage in the criminal justice process. This paper examines prosecutorial accounts for sexual assault case rejection. A central feature of these accounts is discrediting the victim's rape allegation with the techniques of finding discrepancies in the victim's story and assuming ulterior motives for reporting the assault. The resources that prosecutors use to develop these techniques are official reports and records, typifications of rape-relevant behavior, and knowledge of the victim's personal life and criminal connections. Prosecutors' accounts reveal the indigenous logic of prosecutors' decisions to reject cases and the organizational structure in which these decisions are situated. 28 references (Author abstract)
