The use of forensics in criminal investigations is to establish possible guilt or innocence of the potential suspect, linking crime between the suspect…
Forensic Science: fact or pseudo? Three articles, “Forensic Science Controversies” by Rachel Kaufman published in CQ Press, “Forensic Science” from an FBI handbook on Opposing Viewpoints, and “But it Works on TV” by Sharon Begley from Opposing Viewpoints, discussed in this essay have comparing and contrasting rhetorical elements. Those rhetorical elements are the use of factual data from crime scenes (logos and pathos), contrasting writer credibility (ethos), and different appeals to certain audiences through formality of the articles. To begin, the first rhetorical element that all three articles use is factual data from crime scenes and actual information from case files, appealing to the audiences’ logos. By including these facts in the…
“Blood is one of the most significant and frequently encountered types of evidence associated with the Forensic Investigative of death and violent crimes” (James, Kish, and Sutton, 2005 p. 1). A Bloodstain Pattern Analysis is called when bloodstains are found at a violent crime scene. The Bloodstain Pattern Analysis discipline has been in existence for a long time, as early as the late 1800’s. “Bloodstain Pattern Analysis focuses on the analysis of the size, shape, and distribution of bloodstains resulting from bloodshed events as a means of determining the types of activities and mechanisms that produced them” (James, Kish, and Sutton, 2005 p. 1). The Bloodstain Pattern Analysis discipline is an interesting, highly educated career field…
In recent years, television shows such as CSI and NCIS have placed science in the spotlight, frequently depicting forensic science as some type of futuristic magic, unravelling crimes within an hour and without error. Of course, these shows are only fiction. One forensic scientist estimated that “40% of the science on CSI does not exist, and most of the rest is performed in ways that crime lab personnel can only dream about” (Winter & York, 2011). With more than 90 million people watching crime-related shows every week, it is not surprising that the effect of their popularity has become evident in the real world, specifically in real-life criminal trials. Science is bow thought of as a method of catching and convicting criminals, and forensic investigators are basically the heroes who are capable of…
Physical evidence that is left behind in a crime scene plays and important role in reconstructing the various events that took place during the crime . Crime scene reconstruction depends upon joint efforts of law enforcement personnels, medical examiners and criminologist to find the physical evidence and to understand the events that surrounds the occurrence of a crime. If there is a bloodstains then the location and the distribution of the blood stain along with the spatters maybe useful in explaining the events that caused the bleeding. An investigator can decipher from an individual bloodstain, the direction of blood, when it impacted the surface it was deposited on. Bloodstain patterns, consisting of many individual bloodstains…
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…
For years innocent defendants have fallen victims of wrongful convictions, yet agencies such as the Department of Justice (DOJ) have failed to rectify the situation. Not only were the DOJ aware of the evidence that was incorrectly tested, but defendants were never informed that such information existed and they were in fact, innocent. Of the cases involved thousands of victims were said to be guilty and convicted because of faulty testing. Most forensic science consists of ballistics, fingerprints, shoe prints, etc. Although most are accepted among participating parties in court none of them are known to be scientifically reliable.…
The outcomes of a majority of crime scene investigations, which result in the prosecution of a suspect, is dependent upon the tenacity and admissibility of evidence. At trial, the evidence presented can be anything can be evidence that provides direct proof in support of a claim or belief of an assertion to prove or disprove any facts in speculation at trial or controversy, thus confronting flaws with proof or other means to form a conclusion or judgment. Simply put, anything that might have the slightest bearing on the outcome of a case can be broadly classified as evidence, provided it has a logical tendency to relate to the outcome of the case, therefore, in a criminal case, if the matter has a bearing on the guilt or innocence of the defendant,…
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.…
The famous bite mark case of Ted Bundy not only finally created a link to him and his victims, but also set precedent for forensic odontology. Not only was he the first person in Florida to be convicted based on bite marks, but at the time of Bundy’s trial only 17 or 18 states allowed bite mark evidence to be admissible in the court of law and since 1989 all fifty states will now allow bite mark evidence as admissible to the court of law (Tabor 2014). Critics of forensic science techniques and methods often say comment on the inaccuracy of the techniques and methods, and have equated forensic science to just a ‘guessing game’. However, in the Ted Bundy cases, forensic science attached the correct person to the heinous crimes. For instances, the chances of the blood found on Kimberly Leach’s clothes not belonging to Bundy is highly improbable.…
In the article "Examination and Documentation of the Crime Scene" written by George Schiro, he discusses the examination of a crime scene using photography. He states how photography can be used to compare different situations. One example he gives is how actual size photos can be used to compare shoeprints and fingerprints found at the crime scene to possible suspects. These actual size photographs are also known as one-to-one photos. Schiro states in the article that this is an advantage of photography over videography.…
The roots of forensic lead to the Roman era when criminal charges implied public presentation of the case in the Forum. Convicted person for a criminal offense and the applicant, argued publicly about the case, and the person with better arguments and presentation, prevails. Hence the origin of the name forensics, from the Latin word forēnsis which means “in the Forum”. Today, forensic means using full range of science to provide answers to questions of legal interest, relating to criminal or civil proceedings.…
The authors say, “ reliable scientific practices require strict protocols and aggressive oversight to protect against the Annie Dookhans of the world”. The Annie Dookhans of the world are those who have the “win at all costs” mindset and by using that exact number, the author emphasizes their point while pointing out the importance of fixing forensic science. They use strong appeals to logos by providing evidence, stating facts, and giving statistics to back their claim. They point out that, “A 2015 review by the F.B.I. found that its forensic hair-sample analysts testified wrongly in favor of the prosecution 96 percent of the time,” to support their claim that a crime lab is more efficient and reliable if it is independent from law enforcement.…
Investigators could get any type of evidence, but forensic evidence is the only one that can give a person information on how a person died and truthful facts. The safest way to find a criminal would be forensic evidence. The authors choice of forensic evidence will give a person the proof they need to solve a…
Since there is such a growing demand for forensics in general, the forensic students in school are held to I higher expectation. No one will be that interested in having a C average employee determining if a criminal will be sent to prison or to death. That is how they view there training as well. While as an undergrad there are required course; biochemistry, genetics, molecular biology, inorganic chemistry, analytical chemistry, physical chemistry, cell biology, instrumental analysis, pharmacology, and microbiology.…
