Forensic science or just simply forensics is described to be the application of scientific knowledge and techniques. (Bell) The skills of a forensic scientist are used to aid law enforcement in the investigation of a criminal case. Crime scene investigation can be considered a calling that requires the cunning and common sense of the old methods combined with the methods we know now. (Forensic Psycology) A career in forensic science can present many emotional, intellectual, and physiological challenges, but it can also be very rewarding for someone who likes to see justice come to someone who has committed a crime and wants to earn a competitive salary and possibly further their education.
Over the years police work hasn’t changed, but the application of science has. The application of forensics can be traced back to the second century BCE. (The Police Cheif) In 1248, His Duan Yu, a book published by the Chinese described how to distinguish when a person has died from drowning or from strangulation. This was the first recorded application of medical knowledge to the solution of a crime. In 1609, the first written work on systematic document examination was published in France. In 1784, one of the first documented use of physical matching was an Englishmen who was convicted of murder based on the torn edge of a wad of newspaper in a pistol that matched a piece remaining in his pocket.

There are a numerous amount of degrees that can be earned in 2-4 years. Most entry-level careers in forensic science require a bachelor’s degree in forensic or natural science. Earning a masters degree can help get a better job quickly at top salary. This gives experience, education, training, tools, and skills. (Forens...

...being investigated they have to be 100 percent sure that it is the person. There can be no doubt in the results of the testing of evidence that points to the suspect. (Heartland Forensic Pathology)
The science of forensics is now recognized as a critical ingredient in law enforcement and the solution of crimes. Protecting a crime scene from contamination and gathering and interpreting evidence accurately have become some of the most critical ingredients in crime solving. Advances in technology are being applied to the finite and exacting field of forensic science, a field in which technical competency is achieved only by synthesis of a number of factors including training, experience, supervision, continuing education, proficiency and an application of scientific methods and protocols against a background of stringent professional ethics. (Division of State Police)
...igators a lot about a perpetrator it can not tell them his name, where he lives or if he has a previous criminal record. While DNA profiling is not the only forensic tool available, DNA testing technology and improved databases are inspiring investigators and law enforcement agencies to re-open cases that were previously considered unsolvable.
Forensic psychology is a continually adapting sphere. It is hard to have one solid definition for the field, as there are so many aspects that interlock. Within each attribute of the forensic psychology has roles and responsibilities to sustain. The rapid growth and emerging importance of this field volumes of information will be developed in the next decade.
The overall goal of a forensic scientist is to determine the facts using all the available resources they were given. They give their expert opinion to the attorneys, judge, and jury, and depending on how well prepared they are, can sway the jury to either a guilty or innocent verdict (Thinkquest 2014). In general, a forensic expert must keep impeccable records of all that has b...
Forensic Science has contributed to our world a great deal. People often misunderstand Forensic Science and believe it is much more capable than it really is. As a matter of fact what you see on T.V. is around 80% false or over exaggerated in some way. To Start of, Criminal Investigation is the largest and most known form of Forensic Science. Some of the more known areas include; Fingerprinting, Ballistics, DNA Identification, Fiber Samples, Computer Animation, Documentation analysis, etc. To get this out of the way in the beginning, what you saw on last night’s law and order is far from the truth. Things they do in a matter of hours take months at a time, and most of the time aren’t even plausible concepts.
In today’s time, modern Crime Scene Investigation has increased rapidly. From throughout the late 1900’s and in the early 2000’s (Taylor 1). For all of the evidence that they find, a solid foundation has formed over the thousands of years of Crime Scene

Forensic Science, recognized as Forensics, is the solicitation of science to law to understand evidences for crime investigation. Forensic scientists are investigators that collect evidences at the crime scene and analyse it uses technology to reveal scientific evidence in a range of fields. Physical evidence are included things that can be seen, whether with the naked eye or through the use of magnification or other analytical tools. Some of this evidence is categorized as impression evidence2.In this report I’ll determine the areas of forensic science that are relevant to particular investigation and setting out in what method the forensic science procedures I have recognized that would be useful for the particular crime scene.
Forensic scientists work in labs where they examine, identify, and interpret evidence collected in crime scenes. Crime scene investigators collect evidence and pass it to a forensic scientist who uses the items in numerous ways to help catch criminals. Forensic scientists must also record the evidence and any tests run on it in detail to prove the truth in court. A forensic scientist also has to be able to present his or her physical evidence verbally in court, so a strong communication background is important. The first step taken to become a forensic scientist is to first pass the education required to become one.
The transitional growth in the forensic science sector has not been without challenges. Though the world has experienced increased capabilities and scientific knowledge, which has led to faster investigations and results, many forensic experts have argued that forensic laboratory testing, in the light of 21st century technological advancements, is yet to meet the expected rate in quick available testing and analysis (Mennell & Shaw, 2006). This is with respect to the growing rate of crime and the high demand of quick crime scene testing and analysis. In the science of crime scene, analysis and interpretation of evidence is majorly dependent on forensic science, highlighting the change in the role of forensic sciences (Tjin-A-Tsoi, 2013). In the business of forensic science, time is beginning to play important role in the evidence testing and analysis which is becoming crucial in reducing ...
Whereas the real picture of forensic evidence is unlike what is represented in movies and television shows where a fingerprint or a trace of hair is found, then it’s game over for the criminal. Reality is not as straightforward. As more people are exposed to the unreal forensic world through television and media the likeliness for a wrong conviction increases with juries assuming the evidence involves more science than what it really does, this is known as the CSI Effect. Further education and training is needed for the people of the court, the forensic specialists, and so called experts. The people in courts do not question any of the ‘professionals’ and just trust in their expertise. The court could overcome this perception by requiring explanation of error rates in a forensic field. To do this, testing examiner error rates will be necessary which means further research. Forensic science has such a large effect on the prosecution of suspects, experts have been known to provide questionable and at times incorrect evidence. When a false conviction occurs the true perpetrator is set free. Once realized, the public doubts the justice system and the reliability of the forensic evidence even more. At this point in time, forensic is an inexact
Forensic Science, is defined as “the application of science to the criminal and civil laws that are enforced by police agencies in a criminal justice system (Saferstein, 2013).” Analysis of footwear characteristics, impressions, and track ways can provide important evidence in a crime scene investigation.
As far back as 1832, James Marsh was the first to use forensics at trial to give evidence as a chemist in 1832. Since that time forensic science and evidence has come a long way in various ways and technology to help in determine if the suspect is guilt or not, through such things as DNA testing, blood, and fingerprints. The first forensic police crime lab was created in 1910. The contributions of Dr. Edmond Locard, a French scientist and criminologist, proposed that “everything leaves a trace”. This principle is still valid today as it was so many years ago. No matter how small, the specialized trained technicians and investigators can take these methods and go to a crime scene to get evidence. “Forensic science is the application of sciences such as physics, chemistry, biology, computer science and engineering to matters of law.” (Office of Justice, 2017) These different sciences can help achieve and assist in solving a case. Forensic science has also the ability to prove that a crime was committed, it can find the elements of the crime, it can help place the suspect at the scene and whether the suspect had any contact with the victim. However, in the last several years the techniques and with the use of technology the evidence that forensic science uncovers can also exonerate an innocent individual who has been falsely accused of the
According to the American academy of forensic science, the forensic sciences form a vital part if the entire justice and regulatory system. Forensic science is an enticing career having to do with science and criminal justice, a large variety of schooling is needed to start this job Despite the fact that it can be a dangerous environment it can be an exciting profession to pursue. There are many different fields in forensic science that you can study or major in but they all have the same objectives.
“The word ‘forensics’ means “connected with the courtroom”; so forensic science is, therefore, concerned with gathering hard evidence that can be presented in a trial” (Innes 9). Forensic science is a science that is applied specifically to legal matters, whether criminal or civil. “Few areas in the realm of science are as widespread and important as forensic science” (Hunter 12). Forensics is the one science that is most commonly used in everyday life. It is also a branch of science that incorporates other branches of science such as biology, chemistry, and etc. Since it is used almost every day “No one can dispute the importance of the contributions to society made by forensic science; the ability to solve crime is undeniably important” (Hunter 13). Forensic science has given criminal investigation a new edge. “Advances in science have opened the door for more effective evidence discovery, howev...
Forensic science includes all types of different science such as: physics, chemistry, biology, computer science and engineering to matter of law. A forensic scientist is a specialist in a field of science who applies their knowledge to the purposes of law. The job as a Forensic Scientist not only has many details and facts you have to remember but you also need items of evidence that are relevant in order to examine the scene correctly.
