What is The Scientific Method, and How is The Theory...

What is the scientific method ,and how is the theory applied to fingerprint analysis? The complete friction ridge identification process involves using the identification philosophy and scientific methodology in determining whether or not an unknown friction ridge impression(herein, called latent) came from the same source as a known inked print (herein called print)to the exclusion of all others. (1) David Ashbaugh refers to this identification process as, a guide of how friction ridge quantative-qualititive analysis is transformed into an opinion of individuality. It describes the friction ridge formations used during analysis while establishing parameters as to how much knowledge one must have to perform such a task.

These include: *Double taps *Similar shaped ridge path formations *Matrix smears *Colur reversals *Inconsistancies in ridge width *Light or dark areas *Sudden directional change in ridge flow. *Does the lift appear consistant with the surface from which it was lifted?

As such, criminal investigation revolves around three particular questions: 1. who committed the crime? This question is answered based on witnesses, and evidence collection and comparison, 2. how was the crime committed? This question is answered based the use of scientific fields (forensic science) to assess any evidence, and 3. whether the crimeRead MoreDigital Forensics And The Constitution1499 Words   |  6 PagesRiggleman Mount Aloysius College DIGITAL FORENSICS AND THE CONSTITUTION Until recently, forensic scientists needed only to study physical evidence to determine what had taken place at a crime scene. This consisted of gathering fibers and samples of any bodily fluids left behind and also taking note of every aspect of the crimes scene to determine what had happened. In today’s age, that is all still necessary for most crime scenes; however, there is a new frontier for criminals to commit illegal acts. ThisRead MoreIntroduction to Forensic Investigations2352 Words   |  10 Pagesï » ¿Locard’s Exchange Principle and the use of Fingerprints: Edmond Locard (1877-1966) was a French scientist specialised in both medicine and law. Inspired by the work of Hans Gross, it was Edmond that created the concept that all objects of any material should leave traces of itself upon whatever it touches, even if it is the minutest amount, simply put as â€Å"Every Contact leaves a trace,† Locard (1923). This is commonly known as Locard’s Exchange Principle. He believed that in circumstances such asRead MoreEssay on Gathering the Facts at the Crime Scene3234 Words   |  13 Pagesacquit guilty defendants when no scientific evidence has been presented, as they have seen on television.

Today, technology has affected our global surroundings in a number of ways. Technology has created a more advanced society and economy. We use technology in every aspect of life today. New innovations and technology helps create a safer atmosphere and reduces the rate of crime. Technology is the usage and knowledge of techniques or is systems of these things. Usage of technology in the criminal justice system is not new but more apparent todayRead MoreForensic Ballistics3483 Words   |  14 Pagesfirst we will look at forensics itself and how it came about. After getting the basics about the foundation in forensics we will look at ballistics and how the specifics of ballistics started, who is the founder as well as what ballistics consist of. To the best of my ability, we will review different types of test preformed by a ballistic analyst. After gaining all of the knowledge of ballistics and forensics itself, we can then look at detailed steps in how to become a forensic ballist ics analystRead MoreDna Profiling And The Legal System2099 Words   |  9 PagesDNA Profiling In forensics, when using a DNA profile or evidence it has to follow guidelines usually given by the legal system. DNA profiling is a very powerful method used for forensic identification, and there has never been a case where two individuals have the same DNA profile. DNA is a long curved structure, made up of pairs of four specific bases: adenine, guanine, cytosine, and thymine, is the repository of a code from which all of our cells are made. The code is made up of base pairsRead MoreImpact Of Dna Fingerprinting3430 Words   |  14 PagesDNA profiling technologies have had a considerable impact on how forensic science and criminal investigation have been understood, carried out, and regulated in the last 25 years. Current methods of forensic DNA profiling (known also as DNA fingerprinting and DNA typing), based on Polymerase Chain Reaction (PCR) amplifications of a varying number of Short Tandem Repeat (STR) loci found at different locations on the human genome, are regularly described as constituting the â€Å"gold standard for identification†Read More The Implications of DNA Profiling Essay3166 Words   |  13 Pagesof DNA Profiling Former attorney General Janet Reno described our system of justice as a search for the truth.(1) Increasingly, the forensic use of DNA technology is an important ally in that search.
