Improvements in Forensic Science and their Impact
When giving the direction in which Forensic science is heading in the future and its effective on the criminal justice system and the law enforcement community, a simple definition is necessary to start. Forensic science is the applying of science to the criminal and civil aspects of law. It is the gathering of an item, known or unknown, to be analyzed, in a procedural and scientific manner, establishing its evidentiary value in a legal proceeding.
The evolution of Forensic science or what can be said to be the embryotic stage of forensics can be traced back to Archimedes (287–212 BC) who by the request of his king used the law of displacement to determine the purity of a supposedly pure gold crown ("Forensic Science," N.D.). As the world progressed and civilization established laws to govern the populous, so did courts to determine the guilt and innocence of individuals accused of crimes. Most of the beginning forensic methods were not classified as sciences, the rulers of the day employed the knowledge that was common for the day. Such as knowing the way a blade cut the flesh of a pig, and because of this that cut on person meant the same blade was used to injure or kill that person.

We have gone from throwing a little dusk around, taking some photographs, or maybe picking up something discarded to having to know the temperature in which an item can be stored in a refrigerator (Fantino, J. (2016, 04/02/2016). The elements of forensics, especially the relevance and application has become so sophisticated that most law enforcement personnel would not know heads or tails of one type of particular science to another. The education of the responding officer as to the procedures of gathering evidence should be of the utmost priority, as it sets the foundation for the criminal
The author goes on to talk about how technology impacts an investigation and how detectives use technology to collect and record data. Future technology is also discussed in this article and how scientist predict future technology will produce more accurate results in cases. In the world today technology is not always right there is instances where technology have had negative results. This article is current and is a great source for my final project by giving me knowledge on how detectives use technology and science to complete their
Comparing simple techniques simply to retrieve a piece of evidence is completely different as we learn more about the science and learn from the mistakes made in the past. Looking back at the 1800’s and comparing the technology of the 21st century, the difference is certainly huge. The increase in technology makes information more vast and more ideas can be shared easily. Many sciences are based off many “what ifs” while forensic science is more factual and attempt to solve puzzling occurrences and events and get down to what truly
Instead, crime scene investigators in those days used visual inspection of the scene and took samples from any surface that might have contain
Ever since Sherlock Holmes, police and prosecutors have solved cases by confessions or eyewitness accounts, but recently they started solving cases from the forensic evidence found. In the passage, “Forensic Science: Evidence, Clues, and Investigation” by Andrea Campbell, forensic evidence is explained to be the most important evidence to present at trial. Forensic evidence are things like “fingerprints, body fluids, and bullets” (paragraph one). Forensic evidence is the evidence that’s found at the scene of a crime. In paragraph two, it says, “after police have secured the site, criminal investigators collect physical evidence.
This exclaims that without these firm and vital procedures the guilty may go free, or the innocent may be wrongly convicted. People who believe that forensic science is irrelevant and untrustworthy are out of their
DNA evidence has changed the world of criminal justice and has completely changed the way we take evidence from crime scenes. Before DNA we couldn't take things from a crime scene such as blood, fingerprints, hair, fingernails, or dead skin, and link them to someone and place people at a crime scene. DNA evidence was the reason we were able to reopen so many cold cases and solve them and bring victims justice decades after the crime was originally committed. DNA evidence was first introduced in 1985 by British scientist Alec Jeffreys. DNA evidence is the genetic material that is collected from a crime scene or a person and analyzed to identify the source of the DNA.
Previous Cases: For drug processing, we will examine a case that focuses on the supply of controlled drugs. With the help of Forensic Science Service (FSS), it has been engaged in the development of the framework that provides a consistent, robust, and a balanced approach to forensic science casework (G. Booth, 2002). FSS is seen in this case. The case will compare the wraps of two suspected people. The findings are based on the maximum value, clarity, and balance of the product.
The techniques used by the Scientific Expert range from crime scene investigation to giving expert testimonies in courtrooms. Some techniques that are used in crime scene investigation which rely on scientific method include finger print analyses and collecting DNA samples (Liu, 2009). However, using the scientific method regarding the effectiveness of a proposed policy is different. When a new policy is proposed, the Scientific Expert gathers information on said policy such as where the policy has been put into place and compares crime rates before and after it was enforced. Depending on the evidence that is drawn, state or local government look into the policy and make an educated decision concerning whether or not this policy will be successful in the given area.
Collecting and Analyzing Forensic Evidence Collecting and analyzing forensic evidence is a crucial component of any theft from a vehicle investigation. Forensic evidence, such as fingerprints or DNA, can provide valuable information about the perpetrator of the crime. Law enforcement
Science has come a long way over the years. It has helped countless every day struggles and cure diseases most commonly found. What you don’t hear about however is the advancement of forensic science. Forensic science has helped solve countless cases of murder, rape, and sexual assault. In the case of John Joubert, it helped solve the murders of three young boys with one small piece of evidence that linked him directly to the crime.
Forensic Science in the 1920’s was not as high-tech as the Forensic Science of today; with hair comparisons, DNA tests, the testing of bodily fluids, and fingerprinting to identify the person(s) suspected of doing the crime. Forensic Science is the practical application of Science to the law to prove the guilt or innocence of a person. Since its initial application over the years, Forensic Science has helped revolutionize the law and bringing forth of justice. Used in the “perfect crime” to convict two high profile and unlikely people to cause such a horrific crime that caused the pain of a family and a death of a boy who had just started living.
A positive aspect of this is that forensic scientists only need a small amount of a sample to get the results they need (“Forensic Science” 12). These samples can come from many other forms of identification other than fingerprints and bloodstains. A few moderate examples include strands of hair, tiny beads of sweat, and a saliva specimen (“Forensic Science” 12). Forensic Science Technicians stated that “crime scene investigators may use tweezers, black lights, and specialized kits to identify and collect evidence.” They also stated that examining autopsies prove to be beneficial in a crime investigation (“Forensic Science Technicians”
The educational path required to achieve my goal of becoming a forensic scientist will be a long, exhausting process. The different characteristics of forensic science- like the use of analytical techniques- is what sets itself apart from just any other science degree(Thorpe). Being just a junior in high school, KEES money plays a major role in helping me decide where I go
D Assessment DNA technology Forensic testing 24.11.2014 Marius Martinsen 10D Introduction: I have chosen to investigate Forensic testing, it is also known as DNA profiling or genetic fingerprinting. During this essay I will discuss what the disadvantages and what the advantages of forensic testing are. I will also talk about how forensic testing is carried out. Forensic testing is used to identify an individual by using the DNA sequences of that person.
The physical evidences are gathered at any crime scene, for example, hair, fibre, blood, fingerprints, footwear, bare-footprints, tire impressions and any fracture
