Crime scene management and investigation refers to

Crime scene management and investigation refers to the activitythat goes on at an actual crime scene rather than in a forensicslaboratory. However the physical and trace evidence gathered inthe field at a crime scene will eventually be analyzed in aforensics laboratory and the analyses conducted govern the types ofevidence collected at a scene. Many individuals tend to accept asabsolute truth that forensic laboratory testing and results arescientific in nature. However much criticism has been leveled inrecent years that many of the techniques used have never beenvalidated and no known error rates have been established. Withoutthis information we cannot be sure how often forensic examinersmake errors in judgment or to what extent these errors areinfluenced by what the examiner already knows about the case. Thishas broad implications in criminal investigation. For this weeksassignment you will step out of the crime scene and into theforensics laboratory for a look at some known issues and criticismsin forensic laboratory testing as well as in credentialing someoneto be classified as an expert forensic examiner. It is beneficialto understand what happens with the evidence collected at the crimescene once it goes to the laboratory. Your research for this papermay cause you to question the reliability and validity of commonlyrelied upon forensic evidence in criminal trials. However your jobas a scholar (and criminal investigator) is to evaluate objectivelywhat you are learning and arrive at a conclusion that is based oninformation from credible sources. First watch the Frontlinedocumentary The Real CSI and then discuss the following in yourpaper using the National Academy of Sciences 2009 report (Chapters2 4 and 5) as a credible resource to support your assertions:Summarize the Brandon Mayfield case focusing on the idea that notwo fingerprints are alike despite the fact that this has neverbeen tested. Identify what type of testing would need to be done toensure that the assertion that no two fingerprints are alike istrue? Examine whether or not this type of testing is feasible andwhy or why not. Analyze what role cognitive bias might play ininfluencing the forensic lab results of tests in areas such asfingerprint identification firearms identification bite markidentification or the smell of death technique described in theFrontline film. There is much criticism that techniques used infingerprint identification and other types of forensicidentification described in the NAS report (Chapter 5) areinherently unscientific because there have been no validationstudies. Without validation studies that establish known errorrates these methods cannot be said to be scientifically sound.Recommend whether or not to use commonly accepted scientifictechniques that have not been scientifically validated and supportsthese recommendations with research materials. Suggest at least oneintervention to overcome the effects of cognitive bias that mayinfluence a forensic examiners identification decision. Analyzethe type of training and credentials forensic examiners should havein order to work in a forensics lab. Provide recommendations fortraining and credentialing forensic examiners to ensure that theyare adequately trained. The Forensic Identification: Science orPseudoscience?
