If a defendant freely and voluntarily confesses to a crime without inducement, coercion or fear, after having been advised of his constitutional rights, certainly he has not been fundamentally prejudiced. By voluntarily making a statement he has waived his right to counsel and to remain silent. Monts v. State, 218 Tenn. 31, 400 S.W.2d 722.
A voluntary confession can be excluded from evidence. If the accused was not advised of his Miranda rights, illegally arrested, or denied a speedy arraignment, a voluntary confession can be excluded from evidence. These exceptions do not apply if the confession is used to impeach. Note: An involuntary confession may not be used for any purpose.
