The prosecutor in a criminal case shall:

(a) refrain from prosecuting a charge that the prosecutor knows is not supported by probable cause;

(b) make reasonable efforts to assure that the accused has been advised of the right to, and the procedure for obtaining, an attorney and has been given reasonable opportunity to obtain an attorney;

(c) not seek to obtain from an unrepresented accused a waiver of important pretrial rights, such as the right to a preliminary hearing;

(d) make timely disclosure to the defense of all evidence or information known to the prosecutor that tends to negate the guilt of the accused or mitigates the offense, and, in connection with sentencing, disclose to the defense and to the tribunal all unprivileged mitigating information known to the prosecutor, except when the prosecutor is relieved of this responsibility by a protective order of the tribunal; and

(e) except for statements that are necessary to inform the public of the nature and extent of the prosecutor's action and that serve a legitimate law enforcement purpose, refrain from making extrajudicial comments that have a substantial likelihood of heightening public condemnation of the accused and exercise reasonable care to prevent an employee or other person under the control of the prosecutor in a criminal case from making an extrajudicial statement that the prosecutor would be prohibited from making under Rule 19-303.6 (3.6) or this Rule.
