In the investigation stage, lawyers can meet with criminal suspects, provide legal advice to criminal suspects, and represent their complaints and appeals. At the same time, you can learn about the case from the public security organ, put forward your own defense opinions, and apply to the public security organ for bail pending trial according to the case. When the public security organ requests the procuratorial organ to arrest the criminal suspect, it may put forward a defense opinion not to arrest the criminal suspect to the procuratorial organ.
It can be said that in the investigation stage, because there is no case file, in order to understand the case, communication with the public security organs is very important, and it is impossible not to dock with the public security in the important work of obtaining bail pending trial.
