Metrology applied to forensic pattern evidence domains - A call for more forensic science metrology principles

Abstract

Over the last decade, the forensic science community has come under fire for the lack of research demonstrating the validity of conclusions within forensic pattern evidence domains such as fingerprints, firearms, handwriting, and other feature-based comparisons [1], [2]. In 2009, the National Research Council (NRC) first highlighted this issue, stating [t]he simple reality is that the interpretation of forensic evidence is not always based on scientific studies to determine its validity. This is a serious problem. Although research has been done in some disciplines, there is a notable dearth of peer reviewed, published studies establishing the scientific bases and validity of many forensic methods [1].
