The Innocence Of Forensic Evidence Analysis

Improved Essays
When judging the innocence of those accused during a criminal justice trial, do you focus on the forensic science aspects of the hearing? Do you understand what the forensic expert is dictating, or do you simply nod along as they explain what they believe the evidence signifies? Used with the intention to correlate criminal investigations and scientific techniques, forensics became a division of science that specializes in analyzing criminal cases. It has a wide range of disciplines, expanding from DNA laboratory analysis to hair and fingerprint pattern analysis. However, it may not be completely reliable because some of its branches, such as examining hair or soil, may not provide the most solid information. This means that these test conclusions …show more content…
In fact, “the term “forensic science” is used with the recognition that some of these activities might not have a well-developed research base, are not informed by scientific knowledge, or are not developed within the culture of science.” (NCJRS, 2009) Consequently, utilizing forensics as the main reason to accuse someone of a crime can lead to false trials where the wrong person is convicted and possibly sentenced for life or to death. This can truly ruin people’s lives, as they will potentially lose their families, their jobs, and their homes. Therefore, the Innocence Project was created to accurately represent the falsely accused through using DNA tests and falsifying previous evidence that may have been used. It already falsified 349 cases where the wrong person was identified as the culprit. Based on my research, I believe that the criminal justice system does not fairly represent the innocence of individuals, due to its reliance on forensics and …show more content…
This gave rise to many forensic branches, such as arson testing, hair analysis, and semen comparison. However, the most powerful tool with the most potential proved to be DNA testing. This is a technique that can link people to the crime scene through matching and interpreting remaining bodily fluids. However, it also revealed that innocent people have been declared guilty of crimes they were not involved in. Two of the main factors about why this occurs is eyewitness misidentification and the science itself. A huge portion of crime scene analysis is evaluating arson, meaning that the investigators attempt to find the origin of the manmade fire through the leftover marks (Rigby, 2013). However, it is revolved around examining patterns and making assumptions based on the expert’s experience. To prove whether the assumption made by certain patterns were accurate, fire investigators, John Lentini and John DeHaan, conducted a study to test the effects of different fires. In the first part, they used a liquid accelerant to generate a fire- but it created the same pattern as an arson fire. Then during the next part of the study, they realized that the window cracks made from rapid heating, due to the usage of flammable liquid, can also be

    In forensic science, there are multiple things that can point someone as a criminal. In the case of Wayne Williams and the Atlanta Child Murders, hair and fibers were used to convict Wayne Williams. A single hair can contain multiple things that can point a individual to a crime. Hair has certain characteristics that can pinpoint to whom the hair belongs to. Hair of a human will be much thinner compared to animal hair.…

    Finding justice can be hard at times when you can't really seem to find out who did it or why they have done it. Most likely the person will not confess to their crimes. In the passage "Forensic: Evidence, Clues, and Investigation" written by Andrea Campbell, it shows that forensic evidence is one of the most reliable evidences in the court of justice today. These evidences have been practiced for hundreds of years and it is still going strong as of today. The question is, what exactly is forensic science?…

    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).…

    There is also evidence supporting that there may be more innocent people who have admitted guilt in jail due to lack of DNA evidence. The lack of DNA evidence can help the prosecutors case in the event where an individual who admitted to the crime they have not committed wants to appeal his deal. By admitting to the crime, the court believes that this person has admitted to their wrong doing with no evidence to support the defenses appeal, most jury’s would say no innocent man would admit to something they did not…

    Evidence Interpretation Over the years, there have been several cases that have been resolved with a false guilty plea or cases where a guilty party was not convicted of a crime. There are various elements that play a role in solving cases; evidence is a one of these key elements. Many factors can determine if the evidence submitted before a court of law is accurate such as how the evidence is collected, if proper protocell was followed before the laboratory’s handling of the evidence, and if the evidences was accurately processed by the crime scene laboratory by various forensic scientists. 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…

    The results of the study were that “almost half of the surveyed jurors expected the prosecutor to present scientific evidence of some kind in every criminal case. They found that as the seriousness of the charge increases, so does the expectation for scientific evidence. Almost three-quarters of the jurors expected scientific evidence of some kind in cases of murder, attempted murder, or rape. Even in the less serious cases of breaking and entering or theft, a significant number of jurors expected some scientific evidence. Specifically as to DNA evidence, the jurors in the Shelton, Kim, and Barak study had high expectations in the more serious cases, with almost half expecting DNA evidence in murder or attempted murder cases and almost three-quarters expecting DNA evidence in cases charging rape or other criminal sexual conduct” (Barak 153).…

    The use of DNA testing in resolving the inconsistencies in the post-conviction cases was particularly useful, as in these cases, the defendant was long requesting and claiming about his erroneous conviction. The technology was extremely useful for examining the biological evidence and proved extremely beneficial in capital cases by identifying the instances of wrongful convictions (Scheck et al., 2000). Then the study by Edward et al. , during the year 1996 study became the pioneer study that could establish the use of DNA testing in finding conclusive evidence for an innocent being wrongfully convicted.…

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.…
