Never having a need for a defense lawyer I only have what I read and/or see on TV.
My question is....when a person meets with their lawyer do they always tell the whole truth to him/her? I understand the confidentially of the relationship but do the bad guys really tell it all? We see all the time that the bad guys lie to the prosecution and that is to be expected.
How can a defense lawyer 'keep' the laws of the land if he knows his guy has done, let's say, a killing? I don't understand how this fine line of being a lawyer and knowing the laws can allow him to defend someone that has broken the law.
I have a story that the bad guy is a serial killer and his lawyer knows all this. But I can't figure out how this lawyer can defend him. I can not figure out what goes on in his thinking.
Does it take a special mind set to be a defense lawyer? Is that why they get such a bum rap many times?
Thanks ahead of time for any insight you might share.
The American trial process is adversarial in nature; disputing is the process of establishing the facts. Examination and disputing of facts by an adversary serves a similar purpose to peer review in academic journals or independent fact-checking.
Criminal defendants have a right to dispute the facts presented by the state. Many such defendants are mentally disabled, poorly educated, have limited proficiency in English or are otherwise inarticulate. Marginalized people may not be considered trustworthy by people in power. Even people guilty of serious crimes are reasonably entitled to have an advocate involved in the process, so they're not railroaded by the state.
An ethical criminal defense lawyer is a trustworthy intermediary between the criminal defendant and the court or jury. He should be smart enough to recognize flaws and inconsistencies in the prosecution's narrative, and he should be able to deal with the court and the prosecution on behalf of the defendant.
In a criminal trial, the burden of proof falls on the prosecution, which must establish the guilt of the defendant beyond a reasonable doubt. The defense is not required to prove anything at all; the defendant's innocence is presumed and the prosecution must overcome the presumption. If the defendant is guilty, the defense lawyer may be able to throw doubt on testimony of prosecution witnesses in cross examination, dispute the recollection of eyewitnesses, call experts who dispute the findings of state experts, etc.
If the evidence against the defendant is compelling, then a lawyer can examine the process of gathering that evidence. Physical evidence can be improperly gathered, in violation of the defendant's right against unlawful search and seizure. Confessions can be obtained in violation of a defendant's right to counsel and right against self incrimination. The remedy in such situations is exclusion of the evidence from trial, which means that the prosecution can't show that evidence to the jury. Without it, they may not be able to prove guilt beyond a reasonable doubt.
But if the evidence is solid and the police followed the rules, there often isn't much a lawyer can do, other than possibly negotiate a plea agreement. Serial killers don't get acquitted at trial. But there are a number of ways a sentence can be reduced by a plea, and around 90% of criminal cases end with plea agreements. Trials are time-consuming and expensive and juries can reach random conclusions for no reason, so nobody likes going to trial. Prosecutors will be willing to deal in most cases. Even your serial killer might be able to get a deal for life without parole instead of the death penalty, especially if he is willing to confess to all his crimes, which may be unsolved on the books of various law enforcement agencies, or offer the location of the remains of his victims, which families will want recovered for proper burial.
