Forensic Science Essay -- Forensics essays research papers

Forensic Science, also known as Forensics, is the application of science to law. It uses highly developed technology to uncover scientific evidence in a variety of fields. Modern forensic science has a broad range of applications. It is used in civil cases such as forgeries, fraud or negligence. The most common use of forensic science is to investigate criminal cases involving a victim, such as assault, robbery, kidnapping , rape, or murder.   Ã‚  Ã‚  Ã‚  Ã‚   Forensic science is also used in monitoring the compliance of various countries with such international agreements as the Nuclear Non-Proliferation Treaty and the Chemical Weapons Convention and to learn whether a country is developing a secret nuclear weapons program. It can help law enforcement officials determine whether any laws or regulations have been violated in the marketing of foods and drinks, the manufacture of medicines, or the use of pesticides on crops. It can also determine whether drinking water meets legal purity requirements.  Ã‚  Ã‚  Ã‚  Ã‚   The medical examiner is the most important individual in an investigation of a crime involving a victim. It is the responsibility of the medical examiner to visit the crime scene, conduct an autopsy (examination of the body) in cases of death, examine the medical evidence and lab reports, study the victims history, and put all the information together in a report to be turned in to the district attorney. Medical examiners are usually physicians specializing in forensic pathology, the study of structural and functional changes in the body as a result of injury. Their training and qualifications most often include a medical degree and an apprenticeship in a medical examiners office. In the field of forensic science, there are many subspecialties. They include odontology (the study of teeth), anthropology(the study of human beings), psychiatry, biology, chemistry, physics, toxicology (the study of poisons), and pathology (the examination of body tissues and fluids). The medical examiner may call upon forensic scientists who are specialized in these fields for help in a crime investigation. Toxicology is a branch of forensic science that deals with the adverse effects of drugs and poisonous chemicals found in the home, at work or in the environment. All drugs have toxic effect but the effect is most often minor. The toxic effect of drugs... ...d, communities began requiring that coroners have specific academic training. In 1877, Massachusetts replaced the coroners office with the Office of the Medical Examiner, which was to be headed by a physician. Soon many other states followed. In 1915 New York City established a program where the medical examiner was authorized to investigate all deaths that occurred to people who appeared to be in good health, that resulted from criminal violence, accidents, or suicides. Computer technology now allows law enforcement officers o record fingerprints digitally and to transmit and receive information for quick identification. Recent developments in technology allows scientists o examine the deoxyribonucleic acid (DNA) or genetic material of blood, hair, skin, or semen to see if they belong to the victim or the suspected criminal. Using polymerase chain reaction (PCR), a lab can clone the DNA from a very small sample of one of those substances. Forensic science as practiced today is a field of science medicine that uses electron microscopes, lasers, ultraviolet and infrared light, advanced chemical techniques and computerized databanks to analyze and research evidence.
