In criminal cases, different suspects in the same case cannot hire the same defense lawyer. The reason is simple: the lawyer helps the client to clear the charge or reduce the punishment, and the defense lawyer often transfers the criminal responsibility of the client to other suspects, so it is impossible for a lawyer to represent two suspects.
Therefore, in the case of multiple crimes, other criminal suspects have hired defense lawyers, and other criminal suspects must also hire lawyers, otherwise lawyers will put all the criminal responsibility on people without lawyers.
