Answer:
For crime detection and Forensics
Step-by-step explanation:
Forensic science is the combination of two different Latin words: forensis and science. The former, forensic, relates to a discussion or examination performed in public. Because trials in the ancient world were typically held in public, it carries a strong judicial connotation. The second, of course, is science, which is derived from the Greek for knowledge and is today closely tied to the scientific method, a systematic way of acquiring knowledge. Taken together, then, forensic science can be seen as the use of the scientific methods and processes in crime solving.
Despite its ancient etymology, forensic science is anything but old-fashioned. Branches of forensic science are rooted in almost every branch of science and many other aspects of modern society. Because of its ability to find and present objective evidence from areas as diverse as chemistry and accounting, today it is recognized as an essential part of the judicial system.
Essential, why essential?
Because when it comes to cases of life and death, objective evidence is crucial. While key evidence in criminal cases may have come from witnesses or other subjective means in the past, forensic science allows for objective evidence. That means that forensic evidence, based as it is on the scientific method, is seen as more reliable than even eyewitness testimony. In a judicial system which maintains that the accused is innocent until proven guilty, evidence gathered by forensic scientists is now regularly used by both the defense and the prosecution in many court cases.
