The police monitor the scope of the suspect's short message.

What kind of retrieval do you mean? It should be clear whether to synchronize monitoring afterwards. If it is afterwards, you can ask the relevant departments for it. But if it is synchronous monitoring, it is worth discussing.

In addition, Guoan is also a policeman, but according to the authorization of Article 10 of the National Security Law, technical investigation measures can be implemented after strict examination and approval procedures according to the requirements of the national security organs to investigate acts endangering national security.

However, in practice, the police's monitoring of short messages is all-round, and all contents and all people's short messages are within the monitoring range.
