Because when you are looking for a lawyer during detention, you must be accompanied by the case-handling (investigation) personnel before you can meet in the detention center, and you need to go through the relevant formalities in the public security organ. 15 days may not be seen, and the detainee should be interrogated within 24 hours after detention. If it is found that it should not be detained, it shall be approved by the person in charge of the public security organ at or above the county level, and a release notice shall be made. The detention center will issue a release certificate to the detainee with a release notice and release him immediately, so it is best to ask a lawyer after approving the arrest. Article 124 of the Procedures for Handling Criminal Cases by Public Security Organs
Legal objectivity:
Article 34 of the Criminal Procedure Law stipulates that a criminal suspect has the right to entrust a defender from the day when he is interrogated for the first time by the investigation organ or compulsory measures are taken. During the investigation, only lawyers can be entrusted as defenders. The defendant has the right to entrust a defender at any time. When interrogating a criminal suspect for the first time or taking compulsory measures against him, the investigation organ shall inform him that he has the right to entrust a defender. The people's procuratorate shall, within three days from the date of receiving the case materials transferred for examination and prosecution, inform the criminal suspect that he has the right to entrust a defender. The people's court shall, within three days from the date of accepting the case, inform the defendant of the right to entrust a defender. If a criminal suspect or defendant requests to entrust a defender while in custody, the people's court, the people's procuratorate and the public security organ shall promptly convey it. If a criminal suspect or defendant is in custody, his guardian or near relative may also entrust a defender. After accepting the entrustment of a criminal suspect or defendant, the defender shall promptly inform the case-handling organ.
