This book was released on 1996-12-12 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1992 the National Research Council issued DNA Technology in Forensic Science, a book that documented the state of the art in this emerging field. Recently, this volume was brought to worldwide attention in the murder trial of celebrity O. J. Simpson. The Evaluation of Forensic DNA Evidence reports on developments in population genetics and statistics since the original volume was published. The committee comments on statements in the original book that proved controversial or that have been misapplied in the courts. This volume offers recommendations for handling DNA samples, performing calculations, and other aspects of using DNA as a forensic toolâ€"modifying some recommendations presented in the 1992 volume. The update addresses two major areas: Determination of DNA profiles. The committee considers how laboratory errors (particularly false matches) can arise, how errors might be reduced, and how to take into account the fact that the error rate can never be reduced to zero. Interpretation of a finding that the DNA profile of a suspect or victim matches the evidence DNA. The committee addresses controversies in population genetics, exploring the problems that arise from the mixture of groups and subgroups in the American population and how this substructure can be accounted for in calculating frequencies. This volume examines statistical issues in interpreting frequencies as probabilities, including adjustments when a suspect is found through a database search. The committee includes a detailed discussion of what its recommendations would mean in the courtroom, with numerous case citations. By resolving several remaining issues in the evaluation of this increasingly important area of forensic evidence, this technical update will be important to forensic scientists and population geneticistsâ€"and helpful to attorneys, judges, and others who need to understand DNA and the law. Anyone working in laboratories and in the courts or anyone studying this issue should own this book.

Download or read book Misleading DNA Evidence written by Peter Gill and published by Elsevier. This book was released on 2014-06-18 with total page 195 pages. Available in PDF, EPUB and Kindle. Book excerpt: Misleading DNA Evidence: A Guide for Scientists, Judges, and Lawyers presents the reasons miscarriages of justice can occur when dealing with DNA, what the role of the forensic scientist is throughout the process, and how judges and lawyers can educate themselves about all of the possibilities to consider when dealing with cases that involve DNA evidence. DNA has become the gold standard by which a person can be placed at the scene of a crime, and the past decade has seen great advances in this powerful crime solving tool. But the statistics that analysts can attach to DNA evidence often vary, and in some cases the statistical weight assigned to that match, can vary enormously. The numbers provided to juries often overstate the evidence, and can result in a wrongful conviction. In addition to statistics, the way the evidence is collected, stored and analyzed can also result in a wrongful conviction due to contamination. This book reviews high-profile and somewhat contentious cases to illustrate these points, including the death of Meredith Kercher. It examines crucial topics such as characterization of errors and determination of error rates, reporting DNA profiles and the source and sub-source levels, and the essentials of statement writing. It is a concise, readable resource that will help not only scientists, but legal professionals with limited scientific backgrounds, to understand the intricacies of DNA use in the justice system. Ideal reference for scientists and for those without extensive scientific backgrounds Written by one of the pioneers in forensic DNA typing and interpretation of DNA profiling results Ideal format for travel, court environments, or wherever easy access to reference material is vital

Download or read book Introduction to Forensic DNA Evidence for Criminal Justice Professionals written by Jane Moira Taupin and published by CRC Press. This book was released on 2017-07-27 with total page 185 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of DNA profiling in forensic cases has been considered the most innovative technique in forensic science since fingerprinting, yet for those with limited scientific knowledge, understanding DNA enough to utilize it properly can be a daunting task. Introduction to Forensic DNA Evidence for Criminal Justice Professionals is designed for nonscientific readers who need to learn how to effectively use forensic DNA in criminal cases.Written by a forensic scientist world renowned for her expertise in clothing examination, the book provides a balanced perspective on the weight of DNA evidence. Going beyond a simple explanation of the methodology, it arms attorneys and other criminal justice professionals with knowledge of the strengths and limitations of the evidence, including the danger in relying on DNA statistical probabilities in the determination of guilt. The book covers the most common DNA methods used in criminal trials today nuclear DNA short tandem repeat (STR) techniques, mitochondrial DNA, and Y-STR profiling. It helps prosecutors know when to emphasize DNA evidence or proceed with trial in the absence of such evidence. It assists defense lawyers in knowing when to challenge DNA evidence and perhaps employ an independent expert, when to focus elsewhere, or when to secure the advantage of an early guilty plea.By imparting practical and theoretical knowledge in an accessible manner, the book demystifies the topic to help both sides of the adversarial system understand where DNA evidence fits within the context of the case.
Download or read book Inside the Cell written by Erin E Murphy and published by Bold Type Books. This book was released on 2015-10-06 with total page 399 pages. Available in PDF, EPUB and Kindle. Book excerpt: Josiah Sutton was convicted of rape. He was five inches shorter and 65 pounds lighter than the suspect described by the victim, but at trial a lab analyst testified that his DNA was found at the crime scene. His case looked like many others -- arrest, swab, match, conviction. But there was just one problem -- Sutton was innocent. We think of DNA forensics as an infallible science that catches the bad guys and exonerates the innocent. But when the science goes rogue, it can lead to a gross miscarriage of justice. Erin Murphy exposes the dark side of forensic DNA testing: crime labs that receive little oversight and produce inconsistent results; prosecutors who push to test smaller and poorer-quality samples, inviting error and bias; law-enforcement officers who compile massive, unregulated, and racially skewed DNA databases; and industry lobbyists who push policies of "stop and spit." DNA testing is rightly seen as a transformative technological breakthrough, but we should be wary of placing such a powerful weapon in the hands of the same broken criminal justice system that has produced mass incarceration, privileged government interests over personal privacy, and all too often enforced the law in a biased or unjust manner. Inside the Cell exposes the truth about forensic DNA, and shows us what it will take to harness the power of genetic identification in service of accuracy and fairness.

Available in PDF, EPUB and Kindle. Book excerpt: Giving the reader an in-depth understanding of DNA evidence in criminal practice, this text explains in clear language how DNA evidence is obtained and how it can be successfully challenged in court to minimize its impact or even dismiss it completely. Since it first entered the criminal legal practice DNA has become an indispensable tool in fighting crime, as it allows both unambiguous identification of the criminal by traces of biological material left at the crime scene as well as acquitting innocent suspects. This book: outlines the various types of testing used to obtain DNA evidence highlights the weaknesses of DNA testing, presenting and discussing defence strategies for refuting DNA evidence shows how DNA should be treated as just another piece of evidence and how on its own it is often not enough to convict someone of a particular crime. This book is essential reading for students and practitioners of criminal law and practice and forensic science and law.

Available in PDF, EPUB and Kindle. Book excerpt: DNA profiling—commonly known as DNA fingerprinting—is often heralded as unassailable criminal evidence, a veritable “truth machine” that can overturn convictions based on eyewitness testimony, confessions, and other forms of forensic evidence. But DNA evidence is far from infallible. Truth Machine traces the controversial history of DNA fingerprinting by looking at court cases in the United States and United Kingdom beginning in the mid-1980s, when the practice was invented, and continuing until the present. Ultimately, Truth Machine presents compelling evidence of the obstacles and opportunities at the intersection of science, technology, sociology, and law.

Download or read book The Impact of Scientific Evidence on the Criminal Trial written by Oriola Sallavaci and published by Routledge. This book was released on 2014-02-05 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explores challenges posed by the use of DNA evidence to the traditional features, procedures and principles of the criminal trial. It examines the limitations of existing theories of criminal trial processes in the face of increasing use of scientific evidence in the court room. The research elucidates the interconnections at trial of three epistemologies, namely legal reasoning, as represented by counsel and trial judge, common sense manifested by the jury and scientific reasoning expounded by the expert witness. Sallavaci argues that while scientific reasoning is part of this hybrid of trial languages and practices, its extended use is producing specifically novel tensions which impact on the traditional criminal trial landscape. Through the lens of DNA evidence, the book investigates how far the use of scientific evidence in the fact finding process poses challenges for the adversarial character of the proceedings and rules of evidence; how it affects the role of the judge, jury and expert witness, as well as the principle of orality and continuity of the trial. In comparing the challenges faced in English common law trials to those of the USA, this book has international scope, and will be of great use and interest to students and researchers of Criminal Law and Practice, Policing, and the role of Forensics in Law.

Download or read book Using Forensic DNA Evidence at Trial written by Jane Moira Taupin and published by CRC Press. This book was released on 2016-04-21 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: Using Forensic DNA Evidence at Trial: A Case Study Approach covers the most common DNA analysis methods used in criminal trials today, including STR techniques, mitochondrial DNA, and Y-STRs. It presents some novel techniques—including familial testing and analyzing domestic animal hair—that have been recently introduced in unique cases, each of which is outlined in detail. It also illustrates special issues related to forensic DNA evidence by using court proceedings such as trials and appeals, commissions of inquiry, and government and laboratory reviews. With forensic DNA analysis becoming increasingly important at trial, the lively and sometimes bizarre cases presented in this book have been carefully chosen to highlight specific concepts, methods, and interpretations used in DNA analysis. Sections throughout examine the nature of expertise with a special focus on the role of subjectivity in the interpretation of forensic DNA evidence, emphasizing cognitive bias and extraneous context. Using both convictions and exonerations as examples, the book also discusses the strengths and limitations of DNA evidence and testing. The book is written in an accessible manner for the non-scientific reader, such that criminal lawyers, judges, and forensic experts will all understand the nature of analysis and application of DNA evidence in a variety of court cases. Extensive references—including notable trial proceedings, cross references of cases, and specific forensic statistics—round out the book and help to provide a complete understanding of forensic DNA analysis and its current usage in the courtroom.
