According to the provisions of the Criminal Procedure Law, public security organs can take technical investigation according to law for major criminal cases involving national security, which means that only major cases will be located by mobile phones, and if they are major cases, they will not be released on bail pending trial. Generally speaking, during the period of bail pending trial, you should report to the local executive organ regularly, usually on call, and you are not allowed to leave the county where you live without approval, but you will not be monitored in real time.
Trial refers to the process that the judicial organs ask the parties about the case. "Liu Changchuan, History of Song Dynasty" said: "If the campers are scattered, they will fight drunk and tell them to take advantage of them. An imperial envoy arrested Kaifeng and abandoned the city. Open a house and move, ask why without trial.
