Research On Auxiliary Investigation Of Crime By Taking Advantage Of Duty By Psychological Micro-expressions Of Stress Reaction

"Psychological Micro-expressions of stress reaction" is a "response", the full name of Micro-expressions, belongs to the category of psychology, refers to people in the stimulation of the moment, appear on the face, body or language instantaneously stress reaction that cannot be controlled by thought nor disguised. And micro-expressions is a kind of instinct, it is instantaneous reaction, the first reflection when a person was stimulated, and out of control of mind, so it is not can be hide nor disguised, this is human nature. And no one can change or control this instinct reaction. As a whole, "micro-expressions" should include three aspects, the "micro-motion" of the body, "micro-facial expressions" on the face, and language of "micro semantics"."Micro-expressions "comes from psychological stress which can be used to judge the real emotion or to find the lie, those information can be collected to analyze the clue of true facts. Through the comprehensive analysis and test on stimulating stress reaction, then the reverse conclusion of body system internal of the person who was tested can be find out, so one could be "see through" by this way, so it is analysis method of psychological micro-expressions of stress reaction.As the development of analysis method of psychological micro-expressions of stress reaction, it's scientific nature and the use value gradually recognized in different areas, Canada, Japan, Israel, South Korea, Turkey, Russia, Poland, Romania and some other countries also tend to do positive research of this kind of psychological method. By statistics, more than 50 countries around the world use it in different extent. The psychological test results can be case basis of a criminal case in some states of the USA, Japan, Romania and some other countries.Along with the progress of the society, the strengthening of human rights protection in China, the newly revised law formed a new structure. One side, the investigation ability of criminal cases of taking advantage of duty of Public Procuratorate, either of evidence obtaining, and human rights protection are put forward higher request, the other side, those criminal suspector of taking advantage of duty who have advantage of position, relations, background, also can reap the benefit of the internet to get information resources, and it means more countermeasures and stronger resistance of investigation. Searching for new methods of investigation is a prior work, in the future interrogation methods are bound to develop in a direction of "psychological effects". And it is valuable, and can save lots of judicial resources.To form a mode of auxiliary investigating with micro-expressions method to the cases of crimes by taking advantage of duty, should be directed by the empirical case to ascend out of theoretical achievements of judicial practice, then to gain the lie detection model, and the investigation model belongs to the method system, easy to learn, use and promotion. Followed by starts micro-expressions auxiliary function of crime investigation, there are three part of the process, which including certain involved personnel, information collection, application of model. Finally concludes clues from lies through the analysis for the case, and synchronizing to find witness and collect other evidence. It is need to note that one of the most important fact is master the smart way of question asking, that would be magnify the point of micro motion, micro facial expression, micro semantic. Besides of above, it is necessary to keep attention to the case until the end, so to promote the skills.But the micro-expressions analysis technique still have to face the legal problem, it is new, is it effective evidence? For the subjectivity, the conclusion could not be directly use as evidence.Mr. He Jia Hong who is a famous scholar of evidence in China, consider that is appraisal conclusions which could be "limited use" as evidence. And also it is feasible to take the conclusions as "citizen witness" for those relevant experts and professionals. In addition, to practice this method needs advantage resources, human resources, technical resources, so there are still a lot of difficulties and problems. Such as confidentiality issues in the process of investigation that can be solved by confidentiality agreement.There is a good prospect of the auxiliary function of micro-expressions analysis technique in the duty crime investigation, Beijing, Guangzhou and other places of the Public Procuratorate organ have already try to use this psychological way to "reading face" to assist the investigation. With the development of network technology, long-distance arraignment can be realized by the network, and it is the same to the meeting in different places, electronic science and network technology greatly strengthened the investigation ability of Public Procuratorate, the technical platform obviously helpful to achieve the judicial efficiency, shorten the distance of time and space, also provides the experts and professionals effective path. If it is used very skillful, and the benefit be gaited, if not rely it too much in practice, only absorb the active ingredients in scientific research, there will be leap-forward development of investigating crimes by taking advantage of duty. At the same time, it is also a way to increase the degree of scientific investigation.
