A Study On The Application Of Scientific Technologies In Criminal Investigation

Criminal patterns have been shown a lot of new features with the society and technology development.That makes great demands on the deeper theories and actions about criminal investigation.Some methods,those include DNA technology,monitor system used to detect or seek clues,compare with the traces about electromagnetism of communication,the share information and so on,have been used to promote the criminal investigation.Those also indicated that sharing concept played a more important role during the criminal investigation.Modern criminal science and technology is a comprehensive applied subject.It is a floorboard of all technical methods those using physical and social science to disclose,confirm and fight with crime.Narrowly speaking,it includes reconnaissance at criminal scene,obtaining evidences,documents and other evidences examination,testing poison and drugs,forensic medicine,necropsy,clinical test and psychiatry.Broadly speaking,it means that using science and technology during case investigation and crime prevention.At present,most research about modern criminal science and technology are focus on the narrow category studies,which would help to support the police's justice identification.While,the broad category has been more concerned recently.Modern criminal science and technology is a new tool to strengthen police by science and technology.It helps to renew traditional views,improve police's effectiveness and qualities,and ameliorate detective methods.In modem days,detection and breaking cases require assistance of science and technology,so the theories and results of modern criminal science and technology are also the summary of the technical methods of searching and acquiring key evidences and clues.Therefore,it contains not only modem technical equipment,but also the theories and concepts of modern detection.At the same time,it makes demands on workers' high level of technical qualities.This essay will use actual detective cases to find out how modem criminal science and technology would improve traditional detective methods and the rate of breaking cases.
