Can the police find out the contents of the voice call?

Legal analysis: the content of the call can be found out, and so can the call records. After the internal leaders of the police issue relevant documents, they can contact the communication operator to monitor a certain number. In the case of monitoring, the call content and short messages of the parties will be monitored and inquired.

Legal basis: According to Article 52 of the Criminal Procedure Law of People's Republic of China (PRC), judges, prosecutors and investigators must collect all kinds of evidence that can prove the guilt or innocence of criminal suspects and defendants and the seriousness of the crime according to legal procedures. It is strictly forbidden to extort confessions by torture and collect evidence by threats, enticements, deception or other illegal methods, and no one may be forced to prove his guilt. It is necessary to ensure that all citizens who are related to or know the case have the conditions to provide evidence objectively and fully, and they can be hired to assist in the investigation except in special circumstances.
