The role of a Minneapolis criminal defense lawyer is not always to clear someone’s name; sometimes the evidence of guilt is overwhelming and there is little a criminal defense lawyer can do to free his or her client. That does not mean, however, that a lawyer is useless, but rather the lawyer’s job is to ensure the trial is fair and the punishment is appropriate. For many criminal offenses, including sex crimes, a sentence may depend heavily on the evaluation of a mental health professional. In these cases, part of the lawyer’s job is to make sure that the evaluation is unbiased, because if it is not, the defendant could find him- or herself facing a long sentence in prison.
