Book excerpt: The word "ethical” can be defined as proper conduct. A failure of forensic scientists to act ethically can result in serious adverse outcomes. However, while seemingly simple to define, the application of being "ethical” is somewhat more obscure. That is, when is ethical, ethical, and when is it not? Because we have an adversarial legal system, differences of opinion exist in forensic science. However, there are instances when differences are so divergent that an individual's ethics are called into question. In light of not only the O.J. Simpson trial - the first national trial to question the ethical behavior of forensic scientists - and the National Academy of Science critique of forensic science, ethical issues have come to the forefront of concern within the forensic community. Ethics in Forensic Science draws upon the expertise of the editors and numerous contributors in order to present several different perspectives with the goal of better understanding when ethical lines are crossed. In order to achieve this goal, comparisons of various canons of ethics from medicine, law, science, religion, and politics will be examined and applied. Lastly, case studies will be presented to illustrate ethical dilemmas and provide a real-world context for readers. Edited by a well known forensic attorney/consultant and a leading medical examiner, Ethics in Forensic Science addresses the concerns of the entire forensic community - the laboratory, medical examiner, and crime scene investigator. It will be an invaluable reference for practitioners in forensic and/or criminal justice programs, crime scene investigators/photographers, law enforcement training centers, police academies and local agencies, as well as forensic consultants and forensic scientists.
