Can I find the content of the short message directly from the public security bureau?

First, the Public Security Bureau has no records of citizens' communication and short messages; Second, the public security bureau generally does not check the above records, because this is infringement and law enforcement cannot be illegal; Third, for criminal suspects or criminals, after the approval of corresponding procedures, technical investigation measures can be initiated, and call records and short message records can be inquired, including monitoring and recording during the call.
