What is the role of a lawyer?

Safeguard the legitimate rights and interests of the defendant. As defenders, lawyers have their own independent legal status, express legal opinions according to facts and laws, and realize substantive justice and procedural justice. The suspect or defendant will be sentenced to imprisonment, which is only a speculation and may not be sentenced in the end. Even if there is basically no problem with this speculation, the defendant has legitimate rights and interests. For example, whether to extort a confession by torture, whether the victim is at fault, whether to surrender and make meritorious deeds, and so on. In fact, many people think that those prisoners who are sentenced to death will eventually be identified as manslaughter. For example, the case of Nie Shubin in Hebei Province is still in doubt. If you make a mistake, there is still a chance to compensate. What if it's killed by mistake? People can't come back from the dead. An important way to prevent manslaughter is to pay attention to the opinions of defense lawyers. Therefore, lawyers have to defend "death row". Legal basis: Article 35 of the Criminal Procedure Law of People's Republic of China (PRC), defenders put forward materials and opinions on the innocence, light crime or reduction or exemption of criminal responsibility of criminal suspects and defendants according to facts and laws, so as to safeguard the litigation rights and other legitimate rights and interests of criminal suspects and defendants. Article 36 of the Criminal Procedure Law of People's Republic of China (PRC): Defence lawyers can provide legal aid to criminal suspects during investigation; Acting as an agent for complaints and accusations; Apply for changing compulsory measures; Ask the investigation organ about the crimes and cases suspected by the criminal suspect, and put forward opinions.
