The "rescue period" refers to the period from detention to review for arrest, that is, 37 days. After a criminal suspect is detained by the public security organs, the family members may retain a lawyer to go to the detention center to meet and learn about the case, and increase the rate of non-arrest through professional legal acts such as submitting an application for release on guarantee pending further investigation and a legal opinion not approving arrest.
Before the public security organs submit a request for approval of arrest, the lawyer will meet with the parties, communicate and exchange with the police officer in charge, analyze the case from a professional legal perspective, and put forward legal opinions, so as to help the public security organs more fully understand and grasp the circumstances of the case, handle the case objectively and fairly, and promote the public security organ's decision to modify the compulsory measures or withdraw the case.
After the public security organ initiates an approval of arrest, and before the procuratorate makes a decision, the lawyer may submit a legal opinion to the procuratorate not to approve the arrest, and strive to have the procuratorate make a decision not to approve the arrest.
In the practice of handling cases, there are quite a few cases in which the public security do not agree to release the case on bail, report the case to the police, and then the procuratorate makes a decision not to allow the arrest. For criminal suspects whose crimes are minor, such as accomplices, ordinary employees, and criminal suspects who are involved in a small amount of money, these two opportunities for release on bail pending trial within 37 days after detention must be seized.
