Forensic Questioned Document Examinations.
Forensic question document examination is also used to analyze documents that are being disputed. For instance, if there is any question that a document is legitimate, then a question document examiner will analyze the document to determine its validity. This is especially necessary in cases where fraud may be present. In some instances, question document examiners are asked to be witnesses in cases (Koppenhaver, 2007. Southeastern Association of Forensic Document Examiners 2010). To have a clear analysis of forensic question document examination, it is fitting that we look at both the advantages and the disadvantages of this element of forensics.
First, we will analyze the advantages of question document examination. One advantage to using question document examination is that this element of forensics can enable forensic personnel to extract a number of very elaborate and extremely valuable details that will aid in speedily solving crimes and determining whether or not a particular document is fraudulent or valid. . There are a number of different technologies that facilitate this. For instance, there are techniques to determine what types of inks are used to write documents, which not only works wonders in determining validity but can also point to a particular suspect. Techniques, such as “high performance liquid chromatography and infrared spectroscopy with principal components analysis and linear discriminate analysis” facilitate the forensic classification of inks from various ballpoint pins (Kher, 2006). . When one knows the type of ink that has been used to write documents, this will possibly narrow down suspects because efforts will then be focused on analyzing documents written in only that particular ink and looking with pens that contain that particular ink at the crime scene, which will bring forensic personnel one step closer to solving the case.
