Essay on DNA in the Forensic Science Community - 1500 Words
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 alââ¬â¢s research along with three other research articles to review how DNA is collected, the effects that is has on a juror and the pros and cons of DNA collection in the Forensic Science and Criminal Justice community. Keywords: deoxyribonucleic acid, United Statesâ⬠¦show more contentâ⬠¦This paper examines Carrell et alââ¬â¢s research along with three other scholarly research articles to better understand the effects that the DNA recovered from a crime scene has on a particular case and the forensic science co mmunity. In McClure, Weisburd and Wilson (2008) summary article arguing that in addition to bench science, field experimentation involving forensic methods is key to assess the utility of various methods to solve crimes. The study reflected that there is a need for more research into many aspects of forensic science, criticizing the strength of scientific evidence thatââ¬â¢s collected at a crime scene and interpretations of most forensic methods while omitting DNA testing. McClure et alââ¬â¢s (2008) explains that in sexual cases and homicides, the presence of DNA evidence actually increased the likelihood of prosecution and a conviction. According to the article ââ¬Å"â⬠¦the case of convictions, the odds-ratio for the presence of DNA evidence was 33.1 for sexual offenses and 23.1 for homicidesâ⬠(McClure et al., 2008). Subsequently, the research shows that there was a consistent gradual decline in the national homicide rates that began in the 1900s and continued through into the 21st century. The decline of homicides in the US has dropped by from more than 90% in the 1960s to 62% in 2003. Even though this significant drop has occurred during the introduction of the new DNA testingShow MoreRelatedForensic Science : A Forensic Scientist1648 Words à |à 7 PagesIntroduction Topic: Forensic Science In general, a forensic scientistââ¬â¢s job provides an objective, scientific analysis to discover the truth and use that truth in legal proceedings.

The law enforcement community uses DNA profiling to rule out or identify suspects. Unlike hair microscopy, bite mark comparisons, shoe print comparisons, and firearm tool mark analysis, DNA typing has been developed through massive scientific research and has undergone meticulous scientific evaluation (Innocenc e Project). DNA is a foolproof method of identifyingRead MoreThe American Court System And Dna1014 Words à |à 5 PagesThe American Court System and DNA Will the use of forensic DNA in the courts be the equalizer for the wrongly convicted? Per the National Registry of Exonerations, there have been 1,916 exonerations in the United States since 1989 (ââ¬Å"National Registry of Exonerations,â⬠n.d.). Barry Scheck and The Innocence Project have been instrumental in facilitating the exoneration process by presenting forensic DNA evidence to American courtrooms.
