Fear of the False uncovers colonial South AsiaIndia's critical role in the development of forensic science. Around 1900, the government of British India created a web of institutions for the scientific detection of crime. Driven by anxieties about "native mendacity," newly minted forensic analysts focused on uncovering faked evidence planted by South Asians. These experts, joining toxicologists known as "chemical examiners," were supposed to extract objective, scientific truth in the service of British justice. But in trying to expose counteract the presumed tendency of colonized peoples to lie, the new system allowed and encouragedenabled widespread misconduct by state experts, leading toincreasing the risk of wrongful convictions of South Asian defendants. Through scrupulously documented legal cases, Mitra Sharafi reveals that colonial dynamics put special pressure on the relationship between science truth and justice. Examining falsity on both sides of the law through the use of testing to (mis)identify poisons, blood, and semenspermatozoa, as well as debates over adversarialism and inquisitorialism in the colonial courtroom, Fear of the False explores advances in forensic science and shortcuts in criminal procedure against the backdrop of colonial mistrust.
