Do you need a lawyer in criminal cases

It is best to entrust a lawyer to conduct a proper and effective defense in criminal proceedings.

Article 3 1 When a lawyer acts as a defender, he shall, according to facts and laws, present materials and opinions on whether the criminal suspect or defendant is innocent, the crime is light, or his criminal responsibility is reduced or exempted, so as to safeguard the litigation rights and other legitimate rights and interests of the criminal suspect or defendant.
