The Use Of Dna Tests For Hair And Blood Samples - 897 Words

Evidence to Convict Innocent People Scientific breakthroughs now allow the use of DNA tests for hair and blood samples that are about as reliable as fingerprint matching. While the evidence assists law enforcement, it allows defense attorneys to reopen cases to reevaluate solving crimes. Introduction When was the last time you have mistaken someone’s identity? What did the last person in class have on today? Wrongful convictions may begin during the investigative process. Police misconduct or mistaken eyewitness testimony can ruin the rest of a person’s life. The criminal justice system can be changed to prevent the latter by reforming the type of evidence allowed to be used when convicting a person. Most cases of wrongful conviction are either police initiated, which begin with the assumption that a specific person is guilty, or witness initiated, which contains an articulate eyewitness testimony. Police Initiated Police investigations often begin with tunnel vision. Tunnel vision occurs when the police focus on one suspect and do not go through a thorough investigation. Tunnel vision usually obtains biases and the real criminal gets off free. They contain faulty labs, the â€Å"old boy method†, and manufacturing evidence to fill in holes. They also contain police misconduct by the use of snitches (con game), accomplices (turning in of a partner for a lighter sentence), and coerced confessions. Witness Initiated Witness initiated convictions are usually forShow MoreRelatedThe Importance of Dna Evidence1575 Words   |  7 PagesThe Importance of DNA Evidence What is DNA? Is it these winding strands that look like ladders or is it what gives a person blonde hair and blue eyes? Actually, DNA is both of these things. DNA is a person’s genetic makeup–their hereditary blueprint passed on by their parents. It is a part of almost every cell in the human body. In each cell, a person’s DNA is the same; it stays the same throughout their lifetime. DNA is found in skin tissue, sweat, bone, the root and shaft of hair, earwax, mucus,Read MoreDna And Ethics Of Recombinant Dna1601 Words   |  7 Pages Recombinant DNA and Ethics Brooke Boland BIO/410 - Genetics October 23, 2017 Miranda Gauthier Recombinant DNA and Ethics Recombinant DNA technology has become a powerful influence to many fields including medicine, pharmaceuticals and agriculture. Genetic modifications of plants, animals and other organisms have allowed scientists to improve the quality of human life. As genetic engineering continues to rapidly grow, many ethical, social and legal issues arise evaluating the risksRead MoreHair Analysis : Forensic Science966 Words   |  4 PagesProject Trichology is the study of hair. Interestingly, this study dates back to mid-1800s. However, hair analysis in forensic science began in 1930. During which time, a forensic scientist by the name of Edmond Locard introduced the Locard Exchange Principal. This principal hinges on the fact that any time there is contact between two surfaces an exchange of material will take place. (Oien, 2009) In this paper, I will prove how Forensic Hair Analysis and Forensic Hair comparison and studies if properlyRead MoreDna Analysis : Dna Profiling725 Words   |  3 PagesTammy Venhuda Mrs. Paris P.4 English 7-8 10-20-17 DNA Profiling Hook: Have you ever thought about your personal DNA and why it is important to you? Besides showing factors of how you grow, develop, and function, your DNA has more to it. What is DNA profiling? DNA profiling is when someone uses DNA to identify someone, make sure someone is not being wrongly accused, or to claim criminals. But there are pros and cons to DNA profiling. This is because some people are for it and others are againstRead MoreA Brief Look at DNA Profiling1366 Words   |  6 PagesDNA profiling has several advantages in helping solve crimes, however, there are still disadvantages to this technique. DNA profiling can be beneficial, as well as detrimental to the society we live in. DNA profiling has become the most widely used tool in the field of forensics because of the advantages it has to offer, although there are some drawbacks when it comes to utilizing this technique. DNA profiling has greatly enhanced law enforcement investigation by helping determine the suspect i nRead MoreForensic Examination Of Forensic Science1434 Words   |  6 Pagespossibly lead to a suspect. The reliability of forensic evidence testing is a widely debated topic in the world of forensic science. The new â€Å"Gold† standard in evidence is DNA analysis, because of its reliability. Finger printing as well as ballistics are often used but are said to be imperfect compared to DNA analysis. DNA analysis is deemed the most reliable because it has faced rigorous scientific experimentation. Fingerprinting is one of the oldest tool of forensic analysis. Fingerprinting isRead MoreDna Profiling And The Criminal Justice System1372 Words   |  6 Pagesalthough police were able to obtain a semen sample from her murderer the case remained unsolved. In 1986 the killer struck again murdering 15 year old Dawn Ashworth, once again leaving behind semen, but this time the police were able to use DNA profiling to match the semen to a suspect. Colin Pitchfork became the first person to be caught based on mass DNA screening, and the first to be convicted based on DNA profiling.

They determined the three-dimensional structure of DNA, the substance that passes on the genetic characteristics from one generation to the next.

These modules provide Crime Scene Investigation trainees with the adequate information they need to prepare them to know what to look for when looking for blood and hair samples at a crime scene. This also instructs the trainee the significance of how to avoid tampering with evidence and how to properly collect a sample. The men and women trainees have classroom tutorials on the
