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 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.

Palermo explains the “…means of impeding the presentation of sloppy scientific evidence is found Federal Rule of Evidence 403 that gives judges the discretion to admit or to exclude from trial evidence, including scientific, deemed to prejudicial, confusing, or misleading to jurors” (2006). The article then explains that the technical terms used in the trial court while presenting the DNA analyses, is many times too complex for the individuals sitting on the jury. Ultimately, these same jurors are still inclined to reject or accept the facts presented even if they don’t understand the information presented. Palermo also commented on the necessity for better training on the individuals that come in close contact with the collection of DNA evidence, because it’s imperative, as is the training of DNA analysts and others involved with the handling of evidence. The collection of evidence plays a viable role in the process of DNA examination because if evidence isn’t collected properly the evidence could easily be contaminated with other elements from the crime scene. The other elements that may contaminate the crime scene may include but isn’t limited to: officers responding to the crime scene, paramedics, and other emergency personnel that come in contact with important …show more content…

This same article examines the history of DNA evidence and acknowledges that when evidence was first introduced to the courts that the new type of identification was initially accepted without any challenges, however, critics quickly contended that DNA tests were problematic because of the reliability and the validity of probative value of the evidence. For example, DNA exoneration cases suggest that errors in forensic identification led to a high number of wrongful convictions and concerns that media coverage portrayals of forensic science evidence on popular television shows leads jurors to unfairly weigh DNA evidence while making their decision about the facts of a trial (Carrell, 2008). Moreover, in recent DNA exoneration cases the courts and jurors had difficulty analyzing the testimony of the experts on forensic identification evidence. According to the article, in 86 DNA exoneration cases, forensic science testing errors were the second leading cause of wrongful conviction, falling behind wrongful eyewitness misidentification (Carrell,
