在刑事诉讼中,被告人是否有罪,所犯何罪通常是公诉方需要承担证明责任的,由于侦查机关是收集证据的主要机构,所以,在庭审过程中,当对于控方提供的证据有异议时,侦查人员也应该出庭作证。但是因为我国没有侦查人员出庭作证的传统,侦查人员出庭作证在我国的适用还需要不断地完善。本文结合我国的司法实践,对于侦查人员出庭作证制度在我国的具体适用做出了分析和设计,包括侦查人员出庭作证的启动、作证的内容。具体适用的司法程序和相关配套措施的完善,以期此项制度可以在我国的刑事审判中发挥作用。 In criminal proceedings, whether the defendant is guilty of any crime is usually the prosecutor needs to bear the burden of proof.

The specific applicable judicial procedure and related supporting measures are perfect, so that this system can play a role in the criminal trial of our country.
