A Litigator's Guide to DNA educates litigators, judges, criminalists, students, and others about all aspects of the use of DNA evidence in criminal and civil trials. It includes discussions of the molecular biological basis for the tests, essential laboratory practices, probability theory and mathematical calculations. It presents issues relevant to all parties involved in trying a case, from the prosecution and the defense, and to the judge and jury. The book is also extremely useful as a text for students aspiring to careers in forensic science and criminal law. The authors provide a full background on both the molecular biology and the mathematical theory behind forensic tests written specifically for people with little or no science background. No other book relates the foundational information on molecular biology and statistics to legal practice issues as extensively as this book does.
