The defense lawyer clearly knew that the client had committed a crime and defended him.
Lawyers are based on facts, take the law as the criterion, and speak for the interests of the parties from the standpoint of the parties. The power vested in them by law. But when the expert takes action, he knows whether there is action. Lawyer's defense is a paid defense that lawyers strive for the greatest justice and fair power for the defense side and make it get the greatest benefit. The key is to find out the core of the case, treat the symptoms rather than the root cause, don't wear a hat, speak with evidence and convince people.
In principle, lawyers have the obligation of confidentiality, and in order to enable lawyers to perform their confidentiality obligations without worries, the law gives lawyers immunity in this case. Therefore, even if a lawyer knows that a criminal suspect or defendant has committed a crime in performing his defense duties, he needs to keep his mouth shut and does not have to bear legal responsibility for it. Of course there are exceptions.
Will the lawyer be responsible?
Any criminal has the right to ask a defense lawyer to defend himself! Even the murderer that everyone saw! Its purpose is to prevent the tried party from forming a one-sided trial mode from a legal point of view! In other words, the imperial court represents the country and is a person who understands the law. If the party under trial does not understand the law, it may be one-sided and easy to form a false and wrong case! Therefore, we must ask a legal person to defend the law from the perspective of the accused! If the judge is incompetent and the lawyer is competent, the law also allows the defendant to be acquitted. A lawyer never takes any responsibility (unless he cheats)! Because a lawyer has no judicial power, he only defends the person being tried, and the final judgment is in the court, in the judge! Why do you have to bear any responsibility?
