理性看待微表情分析技术在侦讯工作中的应用

Rationally Treat the Application of Micro-Expressions Analysis Technique in Interrogation

微表情分析技术是通过对犯罪嫌疑人进行有效刺激时出现的面部微表情来分析其情绪状态及口供真伪的一项侦查技术,具有判断嫌疑程度、甄别口供真伪、摸透嫌犯心理和扩大侦查线索四大功能,但这些功能的发挥需要同时满足找准基线、有效刺激、顺利捕捉和适当推导四个条件。目前微表情分析技术在个别办案机关已经得到一定程度的应用,并且收到了不错的效果,但要注意应理性应用。

Micro-expressions analysis technique is a kind of investigative technology. It analyzes state of suspects＇ emotion and true or false of suspects＇ confessions by facial micro expressions appearing when suspects are effectively stimulated. Functions of micro-expressions analysis technique can be generalized as judging degree of suspicion, distinguishing true or false of confessions, making clear of suspects＇ psychology and expanding investigative clues. But these functions come into force only when four requirements are satisfied simultaneously, that is, capturing baseline, stimulating effectively, catching successfully and deducing appropriately. So far this technique has applied to some extent to several case handling organs and played a good role. But at the same time, we should put it into use rationally.
