Evolving trend of expert evidence through forensic psychological techniques?

Abstract

Criminology is the study of science, and the criminal justice administration seeks to bring science to the courts through technological advancements. With the growth of science and technology, the amount of scientific expert evidence has been constantly expanding. Recent criminal investigations and trials mostly focus on the science employed by specialists to gather evidence instead of oral evidence. Scientific evidence thus reached before the Court of law by technical methods leads to a significant question about its admissibility. During the trial the expert testimony takes the shape of a view that concerns a scientific problem. It obliges the Court of Justice to thoroughly examine the opinion of the experts and science and find out on what it was founded. The Court must assess the scientific evidence and decide whether, based on the admissibility threshold established by law, the expert's opinion was reached correctly. Forensic psychology has a long history and is an applied area of crime detection in psychology. The technical developments in recent decades have changed the mentality of the perpetrator, which require progress in technology for crime detection. In order to track the psychological elements of suspects and accused engaged in the crime, investigative areas have been extended. The Forensic psychology is now essential to the administration of criminal justice.
