Methods of proof in criminal cases
First, oral evidence is mainly oral statements, supplemented by written statements and transcripts, and key witnesses and appraisers testify in court; Second, physical evidence and documentary evidence should be based on originals, supplemented by photocopies and reproductions; Third, explain when presenting evidence.
The main methods of proof are: key proof, that is, finding joint points and focusing on key plots. For example, whether the defendant in a murder case committed a crime, whether he committed a crime, and whether he entered the scene, so as to achieve remarkable results in grasping the key points. The method of grouping evidence means that several pieces of evidence in a case prove the same direction and can prove a certain fact, so that they can be grouped into a group, and an interlocking combination of evidence can be established to form the same probative force and the same directivity from different levels and angles. Evidence can also be presented in several stages according to the constitutive requirements of the crime or the development stage of the crime, which is convenient for induction. The method of serial proof refers to connecting every indirect evidence that can prove a local situation or individual plot of a case in accordance with the inevitable relationship between them in the absence of direct evidence, and then organizing and presenting the evidence by using logical reasoning knowledge.
