Before forensic evidence is presented in a trial, it must be deemed admissible (Imwinkelried, 1998). The admissibility of evidence is determined by its reliability, its relevance and its legitimacy. The evidence must be screened against the trial court’s Rules of Evidence. The trial court is the deciding factor on the admissibility or inadmissibility of any forensic evidence. The Rules of Evidence are utilized by the courts to determine if either side (Defense or Prosecution), have presented any evidence that may be irrelevant to the case at hand (Imwinkelried, 1998). This means the evidence presented must be absent of prejudice and hearsay.
As potential, future Forensic Scientist, it is important to understand the system of checks and balances that are necessary to introduce forensic evidence in a criminal case. It is also important to be familiar with the case law governing the admissibility of physical evidence. This paper will address the general acceptance criteria governing admissibility, the different categories of evidence, and the court rulings that determine the current standards.
Categories of Evidence.
Evidence can be categorized in many different ways. Evidence can be considered inculpatory or exculpatory (Netzel, Keily & Bell, 2014). This basically means that the evidence presented can either incriminate a suspect or exonerate them respectively. In 1998, Sterling Spann was arrested and imprisoned for murder and sexual assault. Mr. Sterling spent 20 years in prison before the real killer came forth and confessed to the crime (Blume & Helm, 2014). The confession of the real murderer was also corroborated by DNA evidence. In this case the confession of the real killer and the DNA evidence served to exoner...

...ess what qualifies an individual as an expert witness, and is therefore left to the interpretation of the court (Imwinkelried, 1998).
The Concluding Perspective
It is extremely important for a forensic scientists to understand evidence as it pertains to admissibility (Netzel, Keily & Bell, 2014).
The significance of evidence goes way beyond the laboratory. It is imperative that a forensic scientist understand that often times, it is the product of their hard work and diligence that may inevitably determine life or death, freedom or incarceration of an individual.
When findings of the scientist is presented for evidence in court, it is here that the quality, content and relevancy of the findings are most significant. The rules of evidence must be adhered to, and the work produced must be within the guidelines of either the Frye or Daubert standard of admissibility.

The Investigation Of A Crime Essay

- When I enrolled in this course, I had watched a few crime scene shows like CSIU. I considered the investigation of a crime to be like a puzzle. I was curious if what they depict on television is really what happens in an actual crime investigation. In our first assignment, I realized that eye witness memory can be faulty and that up to 87% of wrongful conviction cases are a result of the flawed memory of the testimony of an eye witness. During this first encounter with forensic learning, I also realized the relevance to properly examine, photograph, document and evaluate evidence....   [tags: Forensic science, Fingerprint, Evidence law]

Forensic Evidence Of Forensic Science Essay

- Forensic evidence can provide just outcomes in criminal matters. However, it is not yet an exact science as it can be flawed. It can be misrepresented through the reliability of the evidence, through nonstandard guidelines, and through public perception. Forensic science can be dangerously faulty without focus on the ‘science’ aspect. It can at times be just matching patterns based on an individual’s interpretations. This can lead to a miscarriage of justice and forever alter a person’s life due to a perceived “grey area” (Merritt C, 2010) resulting in a loss of confidence in the reliability of forensic evidence....   [tags: Forensic science, Fingerprint, CSI effect]

Computer Forensics: Issues in Preserving Digital Evidence and Forensic Investigation

- Technology is constantly changing, and as the capabilities change, so do the issues in Forensic information technology (FIT). FIT is defined as the scientific use or application of information technology (IT) that is used to generate and present digital evidence to be used in courts, legal or other formal proceedings (Volonio). While the use of technology helps get things done faster, it also can present many issues if the proper procedures and tools are not used and followed. An existing issue in FIT is computer forensics, in regards to preserving digital evidence and effectively conducting a computer forensics investigation....   [tags: digital media, digital evidence]

Forensic Science And Forensics Science Essays

- Both computer forensic or forensic science and Biometrics sometimes may apply same identification methods; however, they do so for different purposes. Computer forensics or forensics science is based on history and a forensic investigator does not just pick a method in advance. In other words, forensics investigators are unaware of what they will find as evidence. In addition, the manner in which forensics tools and evidence are handled may have critical implications, which can make or break a case....   [tags: Forensic science, Computer forensics]

Computer Forensic Lab Requirements : Computer Forensics Essay

- Computer Forensic Lab Requirements When initially embarking upon the task of defining computer forensic lab requirements, it may seem that the primary focus would reside within the technological portion of the lab simply because the nature of computer forensics is highly technical and complex. However, in reality, it is the structure (physical lab requirements) and the lab policies and processes (many of which are dictated by legal requirements) that actually make a computer forensic lab what it is, rather than simply a building full of high technology equipment and software....   [tags: Computer forensics, Forensic science]

The Effectiveness of DNA Profiling in Forensics Essays

- Forensics has been greatly enhanced by technology. DNA profiling is one of the technologies that has influenced efficiency and credibility of forensic evidence. The FBI first started using DNA in one of its cases in 1988. In Europe, the United Kingdom opened a DNA database in 1955 (Milena, 2006). The main use of the DNA is to compare the evidence collected at crime scene with the suspects. In addition, it helps to establish a connection between the evidence and the criminals. The investigations have been simplified through the use of technology and DNA has been one of the most effective methods in investigations....   [tags: Forensic Evidence, Technology]
