In many jurisdictions, it is the duty of the government to prove a crime. If there is no proof or any reasonable doubt that a crime has been committed by the person on trial, that person is absolved of guilt and released. In the court proceedings, however, it is imperative to have a criminal lawyer to defend you if you are the defendant.
Five objectives are widely accepted for enforcement of criminal law by punishments. These five objectives are retribution, deterrence, incapacitation, rehabilitation and restoration. In short, do not commit the crime if you cannot do the time. No one ever gets away with anything unless there is no proof that they did it. A criminal defense lawyer will try to make any proof disputable.
Under criminal law, government supervision may be imposed and convicts can be forced to conform to guidelines as part of a parole or probation agreement. This can include any number of things the defendant must do, including house arrest. The best criminal defense lawyers, however, can usually get you the best deals with the least amount of guidelines.
So who is a criminal lawyer? Well, there are a whole bunch of different types of lawyers, and only a certain breed are certified to defend criminals in court. Criminal law differs from civil law in that in the latter, the focus is more on resolution and victim compensation than punishment. In criminal law, it is all about punishing the criminal and ensuring the crime does not happen again.
Anyone who is a criminal lawyer only has to dispel the notion that the person they are defending is actually the one who committed a crime. The prosecutor tries to prove actus reus, which is Latin for guilty act, and can be enough to persuade the jury to deliver a guilty plea. Therefore, it behooves a criminal to find the best defense lawyer he or she can, and attempt to fill the minds of the jury with any sort of reasonable doubt.
