Microscopic Hair Analysis Essay

Improved Essays
The innocence project has found “Unverified or improper forensic analysis has contributed to more than 50 percent of its DNA exonerations” (Hughes). More than half of the people exonerated were sentenced because improper or unverified forensic analysis. Microscopic hair comparison and DNA analysis is an issue in the United States' Justice System, however there is a solution.
In 1996, FBI laboratory developed and implemented mitochondrial DNA analysis ("FBI/DOJ Microscopic"). Microscopic hair comparison analyst is a scientific technique used by the FBI Laboratory today ("FBI/DOJ Microscopic"). It is examined both visually and through a microscope ("FBI/DOJ Microscopic"). DNA regions that are examined, are situated between the coding regions in the DNA (Morling). Forensic genetic analysis is used to investigate whether DNA analysis supports assumptions (Morling). Murder, rape and other serious crimes are often solved by DNA investigations (Morling). Before DNA, serology blood typing and microscopic hair comparison were used to help solve cases ("Microscopic

Errors can happen, scientific organizations recommend “that forensic genetic Laboratories be accredited to International laboratory standards”, standards for labs doing measurement and testing (Morling). The National Research Council noted “nearly anyone with a garage and some Capital could theoretically open a forensics Laboratory” (Hughes). Many crime labs in the U.S. have not been accredited by an independent forensic-science organization, only a few states are required too (Hughes). In 154 of 300 DNA exoneration, invalid or improper forensics testing in testimony played a part in the conviction ("Microscopic Hair"). Over 350 people have been exonerated by DNA testing, 18 made it to death row first (Hughes). Hair DNA was enough to convince the jury of Santae Tribble of being at the scene of the murder

    Despite all of the good that using science in criminal investigation has done. Like all things there have been some hiccups. DNA testing has both enhanced and eroded the status of forensic science in criminal cases. Conventional forensic disciplines were unable to identify a perpetrator with any true discrimination. For instance, conventional serology (the study antigen or antibodies) field analysis of blood group substances was largely used in sexual assault cases during the 1980s (Mosby's Medical Dictionary 8th edition, 2009).…

Theses laws have been implanted after wrongful conviction exonerations soared thanks to the Innocence Project. 14 years in prison is the average spent by the wrongly convicted felon, some have even spent time on death row and were thankfully exonerated before their execution.…

Furthermore, with the advances in technology in today’s society, various pieces of evidence such a DNA analysis have been considered a crucial element…

    A suspect may also give a false confession or admission for many different reasons that could lead to the guilt being placed on someone who is truly innocent. The Innocence Project, a group dedicated to exonerating wrongfully convicted individuals through DNA testing and reforming the criminal justice system to prevent future injustice, states that “Too often, forensic analysts’ testimony goes further than the science allows. Many forensic techniques that have been practiced for years – without the benefit of sufficient scientific research – are accepted and repeated as fact. Juries are left with the impression that the evidence is more scientific than it is, and…

    Evidence from thousands of unsolved rape cases and homicides have not been tested for DNA (Willing 1). This shows the problem because there are many cases that have not been tested for DNA when the evidence may be there. About 48,000 of 90,000 rapes in 2000 were not solved due to the lack of DNA evidence (Willing 2). This suggest that with better technology to analyze DNA these crimes could have been solved.…

    The inability to correctly process evidence, especially DNA, can make or break a case. With the necessity of DNA in a murder or rape case is amongst the highest with wrongful convictions and if obtained incorrectly more wrongful convictions can be the result. Additionally training within laboratory technicians can also cause a case to become corrupted. If reports or testing is askew an offender can become incarcerated on faulty science. Prosecutors have also been known to violate the rules of a criminal trial to get a wanted sentence or…

    Lamond wrote this article in 2008 when the forensic science testimony was needed to prove the innocents. And Lamond wrote this article to educate forensic science lovers that the things that they see on the television is not real. The author of this article used special Lexis that only the forensic science students, and people interested in that field can understand the overall meaning that is being applied. The author used the DNA sample as an example to show the differences between the time periods it takes in reality to perform the test, and the time period it is shown in the television. In show the DNA analyzes takes 48 hours, but in reality it takes one to two or more weeks for the result to come.…

    Moreover, the problem cannot be known because occasions when prosecutors drop the case or when people are acquitted after reversals on appeal. While appellate decisions are published and readily available online, the problem with trial acquittals or dropped cases, is that they are not systematically catalogued and made public. 68% of all DNA exonerations have been based in part on mistaken witness identification (Schmalleger & Smykla, 2014). Faulty eyewitness occurs more when there is a cash reward involved. More than half of eyewitnesses switch up their story from the beginning of the trail till the end but still ends up having a major role in the conviction of an innocent individual.…
