This book examines the role of expert witnesses in the legal system and the role of science in the law. The author analyzes the history of science and the law, and demonstrates through modern and historical examples how lawyers routinely use science to secure convictions. She examines the place of scientists in personal injury claims, offering a strong argument that those with the most power and money are able to secure the services of the best experts in order to win cases. Expert Witnesses provides valuable insights into the "behind the scenes" cooperation between lawyers and scientists in the pre-trial construction of cases.
