An overview of forensic science for young adult readers that includes case studies of actual crimes
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.
National survey and state study on consolidation of police services providing information for improvement of state and local laboratory systems. Study of laboratory facilities, equipment and personnel is provided with recommendations for regional laboratories and educational and training programs. An overview of crime laboratory services in Massachusetts is given. Coordination and combination of laboratory services is discussed in connection with state programs which may be established for their improvement.
Forensic Microscopy: A Laboratory Manual will provide the student with a practical overview and understanding of the various microscopes and microscopic techniques employed within the field of forensic science. Each laboratory experiment has been carefully designed to cover the variety of evidence disciplines within the forensic science field with carefully set out objectives, explanations of each topic and worksheets to help students compile and analyse their results. The emphasis is placed on the practical aspects of the analysis to enrich student understanding through hands on experience. The experiments move from basic through to specialised and have been developed to cover a variety of evidence disciplines within forensic science field. The emphasis is placed on techniques currently used by trace examiners. This unique, forensic focused, microscopy laboratory manual provides objectives for each topic covered with experiments designed to reinforce what has been learnt along with end of chapter questions, report requirements and numerous references for further reading. Impression evidence such as fingerprints, shoe tread patterns, tool marks and firearms will be analysed using simple stereomicroscopic techniques. Body fluids drug and trace evidence (e.g. paint glass hair fibre) will be covered by a variety of microscopes and specialized microscopic techniques.
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.
Forensic Science: From the Crime Scene to the Crime Lab, Second Edition, is designed to present forensic science in a straightforward and student-friendly format. Ideal for students with limited background in the sciences, topics are arranged to integrate scientific methodology with actual forensic applications. Discussions are focused on explaining state-of-the-art technology without delving into extraneous theories that may bore or overwhelm non-science students. Only the most relevant scientific and technological concepts are presented, keeping students focused on the practical knowledge they'll need in the field.
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.
