When it comes to forensics, it always feels far from touchable and mysterious profession. Later, with the TVB drama "Forensics" broadcast, let me have a little understanding of this profession. Forensics in criminal investigation is crucial, he is more than clinicians, not only focusing on the "living body medicine", but also to study the "death of medicine". In order to give the unnatural dead a justice, a dignity, but also let the victim can be innocent. The people's right to life is supreme, forensic medicine to protect every citizen's right to life and health from infringement and abuse.
Forensic medicine involves too much content, such as: clinical identification, psychiatric identification, physical evidence identification, toxic identification, pathology identification and so on. Not only that, but also have to investigate a variety of murder scene; civil and criminal cases involving legal events in the living body (person) for damage, labor capacity, gender, sexual function, mental state and other appraisals; testing and identification of forensic DNA evidence related to crime, for individual identification and paternity identification to provide the scientific basis; medical disputes identified; through the toxicological analysis (drug analysis), toxicology (pharmacology) and other means of analytical chemistry, such as toxicology (drug analysis), toxicology (pharmacology) and so on. Pharmacology) and other means of analytical chemistry, the detection of poisoning cases in the type of poison and chemical structure; medical cost reasonableness assessment appraisal; biometrics, forensic anthropology practice using the body's intrinsic physiological characteristics to identify the identity of individuals.
Since we are talking about the duties of a forensic scientist, we have to talk about the tools that forensic scientists use to achieve a wide variety of identifications. The tools of a forensic pathologist include rubber gloves, headrests, scalpels, cords and goggles, including arterial and jugular vein lines. They also have dissection tables, dissecting saws, blades and scalpels. Other tools include x-ray cases, fingerprint sets, bone chisels, hypodermic needles, and scooping spoons.
Let's take a look at what some of these tools do: the autopsy table is used to clamp and hold the body, while carbon dioxide is used to preserve the body to prevent decomposition; the scalpel is used to hold or move the body structure; ropes are used to hold the body in a specific position during the autopsy; the medical examiner uses the dissecting saws and blades to cut through the skin or hard parts such as bones; the speculum is used in the vagina and the rectum for examination; and the fingerprint collection device used to collect fingerprints.Today's leaps and bounds in science and technology have seen forensic examiners utilize a variety of technologies to achieve their goals, such as: alternative light photography, laser ablation, inductively coupled plasma mass spectrometry, radiocarbon, forensic accountant link analysis software, high-speed ballistic photography, and video spectral comparators. Other technologies include: XFT devices, 3D forensic facial reconstruction, magnetic fingerprinting, automated fingerprint recognition, and DNA sequencers. Forensic examiners also use scientific principles (including biology, chemistry, and mathematics) to provide evidence in the courtroom to support the prosecution or defense in civil and criminal investigations. They discover and analyze evidence from a variety of sources, such as blood, fluids, hair, glass fragments, textile fibers, and tire tracks.
Hats off to forensic scientists, a profession that is both intimidating and full of positive energy, not only for bringing justice to the dead, but also for clearing the names of their clients! (New Discoveries in Science and Technology Constantine/Text)
