You should always speak to an experienced criminal defense attorney before making the decision to plead guilty. Even if you want to admit to your crime, a lawyer may be able to secure a more favorable sentence in exchange for your guilty plea. An attorney can also review your case and advise you as to potential legal defenses you may have, including challenging the admissibility of the state’s evidence or challenging the sufficiency of the evidence to prove one or more elements of your charged offense beyond a reasonable doubt.
