The truth is not unimportant, but the truth has nothing to do with lawyers.
Winning doesn't mean that the murderer has escaped responsibility.
In theory, as long as the legitimate rights and interests of the client are not infringed by the other party, the lawyer will type out all the infringing intentions of the other party, which is called winning the case; In fact, as long as the requirements put forward by the client at the time of signing the agreement are fulfilled, it is called winning the case (for example, those who should be sentenced to death should be given a reprieve, and those who should be compensated according to the average amount should be compensated according to the minimum amount, and so on). Of course, if the client's request is to help me get rid of the crime, then I really get rid of the crime and win the case.
For a murderer, the fact is that he killed someone. His lawyer didn't say he didn't kill anyone.
The facts are there.
His lawyer wants to exonerate the murderer for him, and usually points out that the other party's evidence is not enough to prove that the murderer killed someone, that is, you can't prove that my client killed someone. If my client didn't kill someone, the lawyer will never prove his innocence. Innocence needs no proof.
If the existing evidence is not enough to prove that I killed someone, then my lawyer's duty is to try his best to prove that the other party's evidence is insufficient, not to prove that I didn't kill anyone, let alone to expose me for justice and provide the other party with evidence of my murder, so as to bring me to justice.
If my lawyer follows the last rule, he is not a lawyer, but an investigator. In legal affairs, everyone has his own responsibility, not all of us unite to find out the truth. The truth is the investigator's business, not the plaintiff's business, not the defendant's business, nor the judge's business-in a word: the judge's duty is to objectively judge whether the evidence of both the plaintiff and the defendant is true, not to find out the truth. To put it bluntly, the judge's job is to see which of you can stand it.
Therefore, the part involving the truth is only in the police investigation and preliminary examination, but not in other places, and has nothing to do with others.
The situation of taking bribes and bending the law is another problem, which does not belong to the general theoretical category.
