Essential Question: What is legally and ethically expected of forensic scientists & Crime Scene Investigators? Use the following New York Times article for a discussion about the importance of ethics in forensic science at the Houston Police Department Crime Lab. http://www.scientific.org/archive/Houston's%20Troubled%20DNA%20Crime%20Lab%20Faces%20Scrutiny.htm

Forensic Science in the Legal System Essential Question: What is legally and ethically expected of forensic scientists & Crime Scene Investigators? Forensic Science in the Legal System Forensic science = legal matters and legal questions Significant elements in resolving civil and criminal matters Link or exonerate suspects Forensic science, by its very nature, has to do with legal matters and legal questions. Definition of forensic science: the application of science to the criminal and civil laws that are enforced by police agencies in a criminal justice system. Forensic science has emerged as a significant element in efforts to resolve civil and criminal matters in our society. Physical evidence is no longer just used to link a suspect to a crime but it is of equal importance in exonerating a person of guilt. Copyright © Texas Education Agency 2011. All rights reserved.

Forensic Science in the Legal System (continued) Essential Question: What is legally and ethically expected of forensic scientists & Crime Scene Investigators? Forensic Science in the Legal System (continued) Any distinction between civil and criminal is artificial Principles and procedures of the forensic science investigation are the same for both Physical evidence: Recognize Preserve Analyze Forensic science comes to public attention most often as a result of involvement in major criminal cases. From a scientific point of view, the distinction between civil and criminal is artificial—the distinction is a legal one In any type of case, the principles and procedures of the forensic science investigation remain the same. Recognition of physical evidence, its proper preservation, and analysis can often provide important information to courts and juries in helping them resolve the scientific issues. Forensic scientists provide important information to courts and juries, helping them resolve scientific issues. Forensic scientists use scientific procedures to unearth factual information about the physical evidence in a case, regardless of which side the evidence supports Copyright © Texas Education Agency 2011.

Balance of Legal & Ethical Responsibilities Essential Question: What is legally and ethically expected of forensic scientists & Crime Scene Investigators? Balance of Legal & Ethical Responsibilities Science = natural phenomena Law = manmade rules & regulations Science deals with natural phenomena, while law deals with manmade rules and regulations. A forensic scientist not only has to be familiar with the law but also has to appreciate the rules of evidence.

Legal Responsibilities of Forensic Science Essential Question: What is legally and ethically expected of forensic scientists & Crime Scene Investigators? Legal Responsibilities of Forensic Science Follow procedures Obey the rules of evidence Maintain impartiality Stay within the legal, scientific boundaries On the other hand, we also have to follow procedures, obey the rules of evidence, maintain impartiality, and stay within the legal, scientific boundaries. Forensic scientists have to report whatever they observe and whatever they find, no matter what they believe. Report what you observe, whatever you find, no matter what you believe.

Character of Forensic Scientists Essential Question: What is legally and ethically expected of forensic scientists & Crime Scene Investigators? Character of Forensic Scientists Unprejudiced and impartial Objective Have sufficient education and training Forensic scientists are inclined toward the view that their function is to employ scientific procedures to unearth factual information about the physical evidence in a case, regardless of which side the evidence supports. Most forensic scientists think of themselves as unprejudiced and make every effort to ensure that their work is objective. They think of their results as a way of providing information to the court, rather than to one side or the other. Copyright © Texas Education Agency 2011. All rights reserved.

Main Functions of Forensic Science Essential Question: What is legally and ethically expected of forensic scientists & Crime Scene Investigators? Main Functions of Forensic Science Analyze – unearth factual information, regardless which side the evidence supports Interpret – evaluate findings, arriving at opinions and conclusions Report – testify accurately and truthfully Analyze -- use scientific procedures to unearth factual information about the physical evidence in a case, regardless of which side the evidence supports Interpret -- when examining and analyzing physical evidence, forensic scientists must interpret and/or evaluate their findings, arriving at opinions and conclusions Report -- give a report and/or testify on these opinions and conclusions accurately and truthfully Copyright © Texas Education Agency 2011.

Establishing a Professional Standard Essential Question: What is legally and ethically expected of forensic scientists & Crime Scene Investigators? Establishing a Professional Standard An important issue for forensic science Assessment is needed to standardize the collection, examination, and analysis of physical evidence Perhaps the most important issue in the forensic science field is to establish a professional standard. An assessment is needed of standards of practice in the collection, examination, and analysis of physical evidence. Both forensic and legal professions must carefully study their role in examining and presenting scientific evidence in a court of law. Copyright © Texas Education Agency 2011. All rights reserved.
