For twenty-five years‚ the FBI instructed courses involving scientifically flawed information that the FBI examiners mentioned in lab reports and trial testimonies. The FBI mentioned that about ninety percent of microscopic hair analysis reviews contained erroneous statements. In fact‚ FBI agents’ testimonies have contained erroneous statements‚ as well as their submitted lab reports. The National Association of Criminal Justice Defense Lawyers (NACDL) objective was to address statements containing

This paper explores deoxyribonucleic acid (DNA) collection and its relationship to solving crimes. The collection of DNA is one of the most important steps in identifying a suspect in a crime. DNA evidence can either convict or exonerate an individual of a crime. Furthermore‚ the accuracy of forensic identification of evidence has the possibility of leaving biased effects on a juror (Carrell‚ Krauss‚ Liberman‚ Miethe‚ 2008). This paper examines Carrells et al’s research along with three other research

Forensic anthropologists have been under the microscope of whether their ability to identify race is accurate or not. For many centuries‚ there was has been a debate whether race can have biological variations (Ousley‚ Jantz‚ & Freid‚ D‚ 2009‚ p.68). For many centuries there has been a debate whether race can have biological variations (Ousley‚ Jantz‚ & Freid‚ D‚ 2009‚ p.68). Forensic anthropologists are called in to help identify physical characteristics which are then used to determine the physical

When an investigation runs out of ways to identify human remains‚ DNA can play a key role in the identification process. The most common methods of identification by a forensic anthropologist include "detailed skeletal and dental features‚" of the remains‚ but they are sometimes asked to perform DNA profiles as well (Arismendi‚ Baker‚ & Matteson‚ 2004). According to the paper by Arismendi‚ Baker‚ and Matteson‚ when the common modes of identification do not yield any results‚ "DNA typing may provide

When human remains are found in the United States‚ a full investigation goes into the identification of the remains‚ and determining if there was any illegal activities involved in the case. Depending upon the age of the remains‚ tests can be performed to determine identity. For example: if hair is found‚ DNA analysis can be performed for more accurate analysis of race‚ sex‚ height‚ or even identity. One of the most relevant things that could be done in this case‚ is to look at missing person’s dental

District Attorneys Association has supported funding for forensic laboratories to eliminate backlogs in the testing of biological samples from convicted offenders and crime scenes. Funding by the federal government is a critical component in realizing the full potential of DNA testing. (Thimsel‚ 1998). The National District Attorneys Association has always supported the use of DNA testing where such testing will prove the actual innocence of a previously convicted individual and not serve as a diversionary
