A statement, confession, or admission in writing shall not be received in evidence in any criminal proceeding against any defendant unless within a reasonable time of the taking thereof the defendant is furnished with a copy thereof and which statement, confession, or admission shall have endorsed thereon or attached thereto the receipt of the accused or certification of a peace officer which shall state that a copy thereof has been received by or made available to the accused. Nothing in this section requires that a videotape, audiotape, or transcript of a tape be given to the defendant at the time the statement, confession, or admission is made or within a reasonable time thereafter, provided that the videotape or audiotape is available to the defendant or the defendant's attorney for review within a reasonable time of the defendant's arrest, as well as in discovery pursuant to the Rules of Criminal Procedure.
