各类疑难刑事案件的产生与积压是一种客观存在,快速准确查处各类疑难刑事案件是一种客观要求。从理论上推测,设立一种兼具研究和侦查双重职能的专业机构专门应对各类疑难刑事案件,是可行的、必要的和有效的。应从疑难刑事案件研侦机构的定位、组成与运作等方面考虑,成立疑难刑事案件研侦机构。 The emergence and backlog of all kinds of difficult criminal cases is an objective reality. It is an objective requirement to quickly and accurately investigate and deal with various difficult criminal cases. It is theoretically possible to speculate that it is feasible, necessary and effective to establish a specialized agency that combines dual functions of research and investigation to deal with all kinds of difficult criminal cases. From the perspective of positioning, composition and operation of research institutes for difficult criminal cases, the establishment of a research institute for difficult criminal cases should be established.
