Even if there are some scum in the lawyer team, most of them are law-abiding.
What your friend said is: After the public security organ conducts the first interrogation of the criminal suspect or takes compulsory measures according to law, it should inform the criminal suspect that it has the right to hire a lawyer to provide legal advice, and act as an agent to accuse and report, and put it on record.
This is a rule that restricts the behavior of public security organs, not criminal suspects. Even without receiving the notice, the suspect can hire a lawyer himself, and his relatives can also hire him on his behalf.
It will be helpful, and you can provide advice and apply for bail as appropriate.
Before being handed over to the court, it must be investigated, detained and arrested by public security organs and procuratorates. And if the case is complicated, there will be supplementary investigation. Not soon. You can ask about the progress of the case.
Supplement: In addition to waiting for news, compensation for returning stolen goods can be made as appropriate.
