2. The zero confession rule is conducive to the protection of human rights. Its greatest significance lies in awakening people's awareness of rights, that is, respecting the freedom of speech of criminal suspects.
3. It is conducive to preventing unjust, false and wrong cases. Confession has the characteristics of falsehood and variability. If the prosecution is mainly based on confession, then the defendant will often retract his confession at trial. At this time, other evidence often appears loopholes, and due to the limitation of litigation time, it is easy to appear unjust, false and wrong cases. The principle of zero confession can dilute the role of confession, avoid false inducement of confession to public prosecution institutions, improve the accuracy of public prosecution and ensure the authenticity of cases to the greatest extent.
4. It can effectively curb the current phenomenon of extorting confessions by torture, encourage investigators to actively collect evidence and improve the level of investigators.
5. It can solve the problem of lawyers meeting in the investigation stage. In the investigation stage, the investigators blocked lawyers from meeting criminal suspects, mostly because they were under the pressure of extorting confessions by torture, fearing that lawyers would intervene in the criminal suspects' failure to confess or that lawyers would sue the relevant authorities instead of the criminal suspects to extort confessions by torture and expose the phenomenon of extorting confessions by torture. The rule of zero confession is a compromise between the right to silence and the current legal system of criminal procedure. Now, the zero confession rule has been cited by the judicial and public security departments in Fushun, Shenyang, Dalian Jinzhou and other places, and has been evaluated as a historic progress of the judicial system in China. With the popularization of the zero confession rule, the right to silence will become a legislative trend. I think if the right to silence is written into law, it will be "a revolution in China's criminal procedure system".
