从理论上讲,警察出庭作证有着丰富的理论基础及诉讼价值。但在我国,警察以证人身份出席法庭作证尚缺乏立法、理论、观念等诸多方面的足够支撑。毒品案件在侦查、诉讼等环节的种种特殊性,决定了在边防缉毒案件的诉讼过程中需要构建警察出庭作证制度。笔者认为,在边防缉毒案件中构建合理的警察出庭作证制度,需要从转变观念、完善立法、限制缉毒警察出庭作证范围、确立相应的保障体系等方面切入。 In theory, the police testified in court has a wealth of theoretical foundation and litigation value. However, in our country, police still have enough support in many aspects, such as legislation, theory and concept, to attend court testimony as a witness. The various particularities of drug cases in such aspects as investigation and litigation have determined that it is necessary to set up a system of police testifying in court during the litigation of frontier anti-drug drug cases. The author believes that building a reasonable police trial and testification system in the frontier defense and drug warrant cases needs to be changed from changing the concept, perfecting the legislation, limiting the scope for the anti-drug police to appear in court and establishing the corresponding guarantee system.
