从侦查基本理论范畴所具有的意义出发,“纯粹侦查学”和“刑事司法系统”为两种新的研究视角。通过区分事实和法律两个范畴,“纯粹侦查学”的研究视角认为侦查主要解决事实问题,“刑事司法系统”的研究视角对侦查的功能进行了新的界说。 Starting from the significance of investigating the category of basic theory, “pure investigation science” and “criminal justice system” are two new research perspectives. By distinguishing fact from law, the research perspective of “pure investigation” holds that investigation mainly solves factual problems and that the criminal justice system has a new definition of the function of investigation.
