This book exposes the dangerously imperfect forensic evidence that we rely on for criminal convictions. "That's not my fingerprint, your honor," said the defendant, after FBI experts reported a "100-percent identification." The FBI was wrong. It is shocking how often they are. Autopsy of a Crime Lab is the first book to catalog the sources of error and the faulty science behind a range of well-known forensic evidence, from fingerprints and firearms to forensic algorithms. In this devastating forensic takedown, noted legal expert Brandon L. Garrett poses the questions that should be asked in courtrooms every day: Where are the studies that validate the basic premises of widely accepted techniques such as fingerprinting? How can experts testify with 100-percent certainty about a fingerprint, when there is no such thing as a 100 percent match? Where is the quality control at the crime scenes and in the laboratories? Should we so readily adopt powerful new technologies like facial recognition software and rapid DNA machines? And why have judges been so reluctant to consider the weaknesses of so many long-accepted methods? Taking us into the lives of the wrongfully convicted or nearly convicted, into crime labs rocked by scandal, and onto the front lines of promising reform efforts driven by professionals and researchers alike, Autopsy of a Crime Lab illustrates the persistence and perniciousness of shaky science and its well-meaning practitioners.
A rare behind-the-scenes look at the work of forensic scientists The findings of forensic science—from DNA profiles and chemical identifications of illegal drugs to comparisons of bullets, fingerprints, and shoeprints—are widely used in police investigations and courtroom proceedings. While we recognize the significance of this evidence for criminal justice, the actual work of forensic scientists is rarely examined and largely misunderstood. Blood, Powder, and Residue goes inside a metropolitan crime laboratory to shed light on the complex social forces that underlie the analysis of forensic evidence. Drawing on eighteen months of rigorous fieldwork in a crime lab of a major metro area, Beth Bechky tells the stories of the forensic scientists who struggle to deliver unbiased science while under intense pressure from adversarial lawyers, escalating standards of evidence, and critical public scrutiny. Bechky brings to life the daily challenges these scientists face, from the painstaking screening and testing of evidence to making communal decisions about writing up the lab report, all while worrying about attorneys asking them uninformed questions in court. She shows how the work of forensic scientists is fraught with the tensions of serving justice—constantly having to anticipate the expectations of the world of law and the assumptions of the public—while also staying true to their scientific ideals. Blood, Powder, and Residue offers a vivid and sometimes harrowing picture of the lives of highly trained experts tasked with translating their knowledge for others who depend on it to deliver justice.
Forensic Science Investigated takes young readers inside this fast-growing field, showing them how crime scene investigators and forensic specialists gather evidence, solve crimes, and even liberate innocent people who have been mistakenly imprisoned.

Inside the Clark R. Bavin U.S. Fish and Wildlife Service Forensics Laboratory lies a rarely seen world, a CSI for wildlife, where a walk-in freezer contains carcasses and animal parts awaiting necropsies (animal autopsies); shelves and drawers hold pills, rugs, carvings, and countless other products made from parts of endangered animals; and a dedicated group of forensic scientists is responsible for victims from thirty thousand animal species. Accomplished environmental journalist Laurel A. Neme goes behind the scenes at the wildlife forensics lab -- the only crime lab of its kind -- to reveal how its forensic scientists and the agents of the U.S. Fish and Wildlife Service are working to investigate wildlife crimes, protect endangered species, and stem illegal wildlife trafficking, the third largest illegal trade in the world. In three fascinating cases -- headless walrus washed up on the shores of Alaska, black bears killed for the healing powers of their gallbladders, and gorgeous feathered headdresses secretly shipped to the United States from the Amazon -- Neme traces the USFWS's daring undercover investigations and how the scientists' innovative forensic techniques provide conclusive evidence of a crime. Throughout, she underscores the staggering international scope of the supply and demand for wildlife and animal parts. Filled with the suspense and thrilling detail of a crime novel yet driven by the all-too-real drama of a small band of scientists and investigators battling a lucrative, high-stakes underground industry, Animal Investigators is an engrossing account of crime and cutting-edge science.
