Lawyers in criminal cases have little effect. What should I do?

This is of great significance to lawyers in criminal cases. In the investigation stage, the lawyer's primary task is to understand the charges charged by the criminal suspect, the specific investigation organ and the relevant situation of the case from the periphery. After understanding the basic content, lawyers began to study the relevant legal provisions of the crime and local sentencing guidance. Lawyers follow up the progress of the case, communicate the case to the investigation organ, and understand the direction and time limit of the case handlers. In addition, if objective facts exist, lawyers can investigate and collect evidence through legal procedures or apply for investigation and evidence collection according to law to obtain evidence of innocence and guilt of criminal suspects.
