Frye And The Federal Rules Of Evidence Summary

995 Words4 Pages

elt the need to update the rules dealing with presentation of scientific evidence, and did so in the landmark ruling Daubert v. Merrell Dow Pharmaceuticals.This today is still the cited case when dealing with scientific evidence, but we must also observe what led up to Daubert, i.e. Frye and the Federal Rules of Evidence, to allow a greater understanding into the Computer Evidence v. Daubert discussion. In 1923 in the case of Frye, where the evidence in question was that obtained from a device akin to a lie detector test, two important declarations were made by the court. Firstly, judges were awarded the role of gatekeeper having the power to determine what is and is not admissible as evidence. Secondly, it was established that if a scientific …show more content…

However, the opinion of the court did not stop there. Justice Blackmun offered a four-pronged test, employed by most US States even today, which guide judges in assessing acceptance of scientific and technical evidence. The four questions asked, applying to methodology rather than conclusions, should be the following: has the theory or technique been reliably tested, has it been the subject of publications and peer review, what are, if any the known or potential error rates, and finally has the theory been generally accepted as a standard in the scientific community. A few years later in 1999, the Court extended the scope of Daubert to cover technological expertise and to measure the methodology of technologists, thus making Computer Forensics fall within the ambit of the Daubert …show more content…

In the former we find write blockers, and devices that interface with computer components. These can be easily tested and shown to operate correctly. The problem lies in the latter, where software tools are again sub-divided into closed and open sources. A closed-source tool is one where the user is not purchasing software, but rather the right to use the software, involving a restriction of access to the original source code. Thus, forensic investigators, and also the courts, must trust that the vendor creating the software did so accurately, and has properly coded the software so as to obtain reliable results. Conversely, the source code of the software is typically made available in an open source tool, increasing one’s ability to test and assure the reliability of the software, and the accuracy of the results obtained. The National Institute of Standards and Technology provides a working group testing disk imagining tools that may be used in computer forensics, ensuring that the requirements are met. This is however merely one type of tool which is being tested, and whilst it is a step in the right direction, bodies such as the national institute of standards and technology do not assume liability for any results, nor do they certify

Iso 5725 Criteria For Computer Forensics

724 Words | 3 Pages

The very first step after identifying and selecting the required computer forensics software our company needs, we need to test, verify, and validate the software otherwise the evidence we present would not be admitted in court. In the company, one of our main goals is to always follow the established standards set by federal agencies. For this purpose, when planning our procedure to validate our software, we must meet the standards set by the National Institute of Standards, and Technology, also known as NIST, which creates procedures and criteria for testing and validating computer forensics software and tools. In order to verify, test and validate the forensic software the company will be using we need to meet the criteria established by NIST in 2001 based on standard testing methods, the ISO 17025 criteria for items that have no current standards and the ISO 5725 criteria.

Pros And Cons Of The Daubert Standard

1404 Words | 6 Pages

Under the modified Daubert standard, relevant scientific evidence is only admissible if it is centered upon testable hypotheses, conforms with the standard rate of potential errors, has been peer reviewed, and if the method is generally accepted in the scientific community (Hoog, 2008). However, there are three problems with the application of the Daubert standard. Firstly, David E. Bernstein and Jeffrey D. Jackson (2004) proved that there was no uniformity in the application of the standard in the sense that it’s only abided with in a portion of the states, and not necessarily with full adherence. Secondly, since the judge is not a scientist, it is difficult for him/her to, without doubt, determine the full honesty of the experts’ testimonies. An example from the Willingham case would be the two medical experts asserting that he was a sociopath although one was an irrelevant family counselor and the other, known as “Dr. Death” and later expelled from the American Psychiatric Association for ethical violations, had not even spoken to Todd Willingham.

Today, modern standards require the burden of proof be brought forth by the plaintiff, or prosecution in criminal cases. This means that the accused no longer has to prove they did not commit the crime, but the prosecution has to prove that all the evidence proves the accused did in fact commit the crime in question. Circumstantial evidence is not enough, but physical evidence, or forensic evidence is now required in modern courts for a conviction. Additionally, the modern standard when considering evidence, and for conviction is “beyond a reasonable doubt.”

Dynamic Symbolism Of Legal Sciences

Well before criminal examinations joined the utilization of fingerprints, archive examination, blood splash design investigation, gunfire directions, mishap recreation, and so forth, these were the subjects of fiction. Most commonplace to numerous, Sherlock Holmes and his accomplice, Dr. Watson, connected the logical strategy and stellar analyst work to settle violations and consequently acquainted these ideas with the majority. Extensively, this is the meaning of scientific science: applying science and innovation to lawful examinations, regardless of whether common or criminal. From the "medicolegal" examination of a human body posthumous (after death) to investigating the breath of a driver who had a couple of an excessive number of beverages, the reproduction of how the Twin Towers crumbled, and the recognizable proof of obscure troopers and regular citizens in combat zones in mass graves, these practices have now long been coordinated into Westernized contemporary court and equity frameworks. However, it was just in late decades that the capacities of measurable researchers have limitlessly extended because of a renaissance of logical leaps forward.
