The job of a criminal lawyer isn’t to see justice served—that is the job of the judge and jury. Neither is it to see the accused be subject to punishment—that is the job of the prosecution. Instead, the job of the criminal lawyer is to defend his client, committing himself (or herself) fully to that role. It is only when all three parts of the criminal justice system do their jobs to the best of their abilities that the system as a whole works as it is intended—that is, to test the truth in each case.
If a criminal lawyer were to give up his duty to defend, then justice becomes skewed in favor of the prosecution, and the right to a fair trial is likely to be lost in the process. The defendant’s case, needless to say, rests on the determination and capabilities of the defense lawyer. It is imperative, therefore, that the criminal lawyer is fully knowledgeable of the various defense strategies that may be applied to his client’s particular case.
The quest for acquittal, however, is not always achieved, nor is it guaranteed. Sometimes, a criminal lawyer, in order to best serve the client, might suggest a compromise or plea bargain, working on either settlements or mitigating penalties. Whatever the outcome, the criminal lawyer is expected to keep his client's best interests in mind at all times.
