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.

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.

As war rages, both sides are in a race to find the one thing that could turn the tides to their favor -- a stone with the power to turn humans into gods -- in the second book of Brian McClellan's epic fantasy tale of magic and gunpowder. The country is in turmoil. With the capital city occupied, half a million refugees are on the march, looking for safety on the frontier, accompanied by Lady Flint's soldiers. But escaping war is never easy, and soon the battle may find them, whether they are prepared or not. Back in the capital, Michel Bravis smuggles even more refugees out of the city. But internal forces are working against him. With enemies on all sides, Michel may be forced to find help with the very occupiers he's trying to undermine. Meanwhile, Ben Styke is building his own army. He and his mad lancers are gathering every able body they can find and searching for an ancient artifact that may have the power to turn the tides of war in their favor. But what they find may not be what they're looking for. Continue the pistol-packing fantasy series by the author whose debut novel Brandon Sanderson called "just plain awesome!"

As witnessed in landmark criminal cases, the quality and integrity of bloodstain evidence can be a crucial factor in determining a verdict. Since the first edition of Interpretation of Bloodstain Evidence at Crime Scenes was published nearly a decade ago, bloodstain pattern interpretation has continued to grow as a branch of forensic science. Revised and updated to reflect new technology and developments in the field, the second edition is packed with new information and illustrations-including 421 photographs and diagrams of improved quality that will aid in interpretation of evidence. Expanding on a single chapter presented in the bestselling first edition, the second edition details, in four chapters, an introduction to bloodstain interpretation; low-velocity impact and angular considerations; medium and high-velocity impact; and the significance of partially dried, clotted, aged, and physically altered bloodstains in four new chapters. A full chapter on the detection of blood with luminol, featuring high-quality, full-color photographs of luminol reactions, has been added. This new edition also includes 12 new case studies in addition to 8 original case studies from the first edition that have been retained for their interpretative value. Everyone involved in crime scene evaluation and interpretation-law enforcement officers, criminologists, medical examiners, forensic pathologists, medicolegal personnel, and prosecutors and defense attorneys-will benefit from the improved and expanded second edition of this definitive reference.
