How do criminals contact lawyers?

As long as they are relatives, even friends, they can be entrusted. There is no law that only parents can invite. It is suggested to communicate with the public security organs here, not the police station, but the legal department or the legal department of the public security bureau. If it still doesn't work, go to the local procuratorate, and they will come forward to safeguard the legitimate rights and interests of the criminal suspect.
