在犯罪侦查实践中,由于犯罪行为的复杂性,犯罪侦查主客体各方面的原因,使得相当一部分犯罪案件久侦难破。针对疑难案件的特点,侦查人员要坚定信心,不破不休;集思广益,解析疑点;跳出窠臼,拓展思路;收集线索,力争并案;加强协作,合成作战。 In the criminal investigation practice, due to the complexity of criminal behavior, the causes of the subject and object of criminal investigation make a considerable part of the criminal cases difficult to detect for a long time. In view of the characteristics of difficult cases, investigators should strengthen their confidence and never stop breaking through each other. They should pool their wisdom and resolve doubtful points. They should work hard to expand their thinking and collect clues to strive for mergers and acquisitions. They should also strengthen collaboration and synthesize operations.
