First of all, the lawyer needs to submit an application to the public security agency, which will review and approve it. Under normal circumstances, the public security organs will require lawyers to submit legally binding documents, such as lawyer's practice certificate, power of attorney and other documents. Before submitting an application, lawyers should understand the relevant regulations and procedures of the local public security agency.
Secondly, when lawyers meet with criminal suspects, they must abide by laws, regulations and relevant provisions, safeguard the legitimate rights and interests of criminal suspects, and must not leak secrets, interfere with investigation work, or help criminal suspects evade legal investigation. Specifically, lawyers must strictly adhere to professional ethics during interviews, refrain from questioning, and must not disrupt the order of investigations or interfere with the normal law enforcement and notarization activities of public security organs. They must also conscientiously fulfill their obligations to properly handle illegal and criminal acts and maintain fairness and justice.
Finally, special attention must be paid not to reveal the suspect's privacy and confidential information during the interview, not to carry any illegal or illegal items or other related items, and not to participate in any activities intended to break the law. Violators will be prosecuted.
