Legal analysis: the rule of evidence exclusion means that it is forbidden to extort confessions by torture and collect evidence by threats, enticements, deception and other illegal methods, and no one can be forced to prove his guilt. In sentencing all cases, we should attach importance to evidence, investigation and research, and we should not trust confessions.

Legal basis: Article 56 of the Criminal Procedure Law of People's Republic of China (PRC) stipulates that confessions of criminal suspects and defendants collected by illegal methods such as extorting confessions by torture, witness testimony and victim statements collected by illegal methods such as violence and threats shall be excluded. If the collection of material evidence and documentary evidence does not conform to legal procedures and may seriously affect judicial justice, it shall be corrected or a reasonable explanation shall be made; If it cannot be corrected or a reasonable explanation cannot be given, the evidence shall be excluded. Evidence that should be excluded during investigation, examination, prosecution and trial shall be excluded according to law and shall not be used as the basis for prosecution opinions, prosecution decisions and judgments.
