Forensic Science Errors and Wrongful Convictions: Case Studies and Root Causes provides a rigorous and detailed examination of two key issues: the continuing problem of wrongful convictions and the role of forensic science in these miscarriages of justice. This comprehensive textbook covers the full breadth of the topic. It looks at each type of evidence, historical factors, system issues, organizational factors, and individual examiners. Forensic science errors may arise at any time from crime scene to courtroom. Probative evidence may be overlooked at the scene of a crime, or the chain of custody may be compromised. Police investigators may misuse or ignore forensic evidence. A poorly-trained examiner may not apply the accepted standards of the discipline or may make unsound interpretations that exceed the limits of generally accepted scientific knowledge. In the courtroom, the forensic scientist may testify outside the standards of the discipline or fail to present exculpatory results. Prosecutors may suppress or mischaracterize evidence, and judges may admit testimony that does not conform to rules of evidence. All too often, the accused will not be afforded an adequate defense—especially given the technical complexities of forensic evidence. These issues do not arise in a vacuum; they result from system issues that are discernable and can be ameliorated. Author John Morgan provides a thorough discussion of the policy, practice, and technical aspects of forensic science errors from a root-cause, scientific analysis perspective. Readers will learn to analyze common issues across cases and jurisdictions, perform basic root cause analysis, and develop systemic reforms. The reader is encouraged to assess cases and issues without regard to preconceived views or prejudicial language. As such, the book reinforces the need to obtain a clear understanding of errors to properly develop a set of effective scientific, procedural, and policy reforms to reduce wrongful convictions and improve forensic integrity and reliability. Written in a format and style accessible to a broad audience, Forensic Science Errors and Wrongful Convictions presents a thorough analysis across all of these issues, supported by detailed case studies and a clear understanding of the scientific basis of the forensic disciplines.

Imagine being convicted of a crime you didn't commit and spending years behind bars. Since 1989 more than 1,400 Americans who experienced this injustice have been exonerated. Some of the people who have won their freedom include Ronald Cotton, who was falsely convicted of raping a college student; Nicole Harris, who was unjustly imprisoned for the death of her son; and intellectually disabled Earl Washington Jr., who was unfairly sentenced to death for the rape and murder of a young mother. Wrongful convictions shatter lives and harm society by allowing real perpetrators to potentially commit additional crimes. How can such injustices happen? Overturning Wrongful Convictions recounts stories of individuals who served someone else's prison time due to mistaken eyewitness identification, police misconduct, faulty forensic science, poor legal representation, courtroom mistakes, and other factors. You'll learn about the legal processes that can lead to unjust convictions and about the Innocence Project and other organizations dedicated to righting these wrongs. The sciences—including psychology, criminology, police science, and forensic science—work hand in hand with the legal system to prosecute and punish those people whose actions break laws. Those same sciences can also be used to free people who have been wrongfully convicted. As a society, can we learn from past mistakes to avoid more unjust convictions?

The magnitude of wrongful conviction is increasing across the country and around the world, with individuals arrested, convicted, and incarcerated for extended periods of time. This book provides an understanding of legal remedies, organizational reforms, and policy changes that have been proposed and implemented. In various jurisdictions, these procedures reduce the likelihood of a wrongful conviction. Legal and organizational reforms and changes in criminal justice policy are considered at three key junctures of the process: (1) the investigation, evidence gathering, and forensic analysis, (2) prosecutorial decision-making, and (3) the judicial review and exoneration of a wrongfully convicted defendant. Each chapter opens with a wrongful case vignette that illustrates the reform strategies being considered. The investigatory process is studied on each case, and the police process is analyzed in detail. Part 1 includes the introductory chapter that provides an overview of wrongful convictions, and the investigatory process routinely employed to gather evidence and identify a suspect. The analysis of forensic evidence is explored, including the chain of custody, contamination of the evidence, misinterpretation, and the falsification of forensic reports. Part 2 focuses on the prosecutors, defense attorneys, judges and juries. Plea bargaining strategies, coaching witnesses, violations of the rules of discovery, use of jailhouse snitches, inadequate defense counseling, lack of preparation and adequate resources are examined. Part 3 analyzes the processes involved in the reversal of wrongful convictions, the judicial review, and obstacles encountered in the exoneration process. In addition, the authors provide a thorough analytical overview of the criminal justice processes involved in wrongful conviction and the reforms that are needed to prevent and reverse injustices. This book is an invaluable resource for prosecutors, defense attorneys, judges, advocates for the wrongfully convicted, criminal justice policymakers, law and society, and will contribute to academic courses in the fields of criminology and justice.

This innovative work builds on Huff and Killias’ earlier publication (2008), but is broader and more thoroughly comparative in a number of important ways: (1) while focusing heavily on wrongful convictions, it places the subject of wrongful convictions in the broader contextual framework of miscarriages of justice and provides discussions of different types of miscarriages of justice that have not previously received much scholarly attention by criminologists; (2) it addresses, in much greater detail, the questions of how, and how often, wrongful convictions occur; (3) it provides more in-depth consideration of the role of forensic science in helping produce wrongful convictions and in helping free those who have been wrongfully convicted; (4) it offers new insights into the origins and current progress of the innocence movement, as well as the challenges that await the exonerated when they return to "free" society; (5) it assesses the impact of the use of alternatives to trials (especially plea bargains in the U.S. and summary proceedings and penal orders in Europe) in producing wrongful convictions; (6) it considers how the U.S. and Canada have responded to 9/11 and the increased threat of terrorism by enacting legislation and adopting policies that may exacerbate the problem of wrongful conviction; and (7) it provides in-depth considerations of two topics related to wrongful conviction: voluntary false confessions and convictions which, although technically not wrongful since they are based on law violations, represent another type of miscarriage of justice since they are due solely to unjust laws resulting from political repression.

Presents stories of individuals who served someone else's prison time due to mistaken eyewitness identification, police misconduct, faulty forensic science, poor legal representation, courtroom mistakes, and other factors.

Understanding Wrongful Conviction: How Innocent People Are Convicted of Crimes They Did Not Commit identifies and discusses breakdowns in the criminal justice system that can have profoundly negative effects on individuals operating within or who are subjects of the system. The text also explores what can be done to successfully reduce the incidence of wrongful conviction. The opening chapter defines wrongful conviction, explains the importance of its study, and provides readers with context as to how often it happens within the American criminal justice system. Readers are provided with an overview of the history of wrongful conviction and the innocence movement. They read chapters that describe how errors and misconduct related to eyewitness testimony, forensic science, false confessions, false accusations, police error, prosecutorial error, and defense attorney error can lead to wrongful convictions. The final chapters address the aftereffects of wrongful conviction and what can be done to reduce instances of wrongful conviction. Providing readers with a unique and critical perspective, Understanding Wrongful Conviction is an ideal resource for courses and programs in criminal justice. Robert J. Ramsey, Ph.D. is an associate professor of criminal justice at Indiana University East, where he directed the Criminal Justice Program for 10 years. He holds a B.S. in political science from Miami University and a M.S. and Ph.D. in criminal justice from the University of Cincinnati. Dr. Ramsey has published articles and book chapters on the topic of wrongful conviction in Forensic Science, Crime and Delinquency, Journal of the Institute of Justice and International Studies, and Criminal Justice, and has spoken at numerous professional conferences about wrongful conviction. His professional research interests include wrongful conviction, community corrections and restorative justice, faith-based correctional interventions, reentry, and Judeo-Christian bases of the law.

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.
