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, counsel and has been given reasonable opportunity to obtain counsel;
(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;
(e) not subpoena a lawyer in a grand jury or other criminal proceeding to present evidence about a past or present client unless the prosecutor reasonably believes:
(1) the information sought is not protected from disclosure by any applicable privilege;
(2) the evidence sought is essential to the successful completion of an ongoing investigation or prosecution; and
(3) there is no other feasible alternative to obtain the information;
(f) 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 investigators, law enforcement personnel, employees or other persons assisting or associated with the prosecutor in a criminal case from making an extrajudicial statement that the prosecutor would be prohibited from making under Rule 3.6 or this Rule.
 A prosecutor has the responsibility of a minister of justice and not simply that of an advocate. This responsibility carries with it specific obligations to see that the defendant is accorded procedural justice and that guilt is decided upon the basis of sufficient evidence. Precisely how far the prosecutor is required to go in this direction is a matter of debate and varies in different jurisdictions. Many jurisdictions have adopted the ABA Standards of Criminal Justice Relating to the Prosecution Function, which in turn are the product of prolonged and careful deliberation by lawyers experienced in both criminal prosecution and defense. Applicable law may require other measures by the prosecutor and knowing disregard of those obligations or a systematic abuse of prosecutorial discretion could constitute a violation of Rule 8.4.
 In some jurisdictions, a defendant may waive a preliminary hearing and thereby lose a valuable opportunity to challenge probable cause. Accordingly, prosecutors should not seek to obtain waivers of preliminary hearings or other important pretrial rights from unrepresented accused persons. Paragraph (c) does not apply, however, to an accused appearing pro se with the approval of the tribunal. Nor does it forbid the lawful questioning of a suspect who has knowingly waived the rights to counsel and silence.
 The exception in paragraph (d) recognizes that a prosecutor may seek an appropriate protective order from the tribunal if disclosure of information to the defense could result in substantial harm to an individual or to the public interest.
 Paragraph (e) is intended to limit the issuance of lawyer subpoenas in grand jury and other criminal proceedings to those situations in which there is a genuine need to intrude into the client lawyer relationship.
 Paragraph (f) supplements Rule 3.6, which prohibits extrajudicial statements that have a substantial likelihood of prejudicing an adjudicatory proceeding. In the context of a criminal prosecution, a prosecutor's extrajudicial statement can create the additional problem of increasing public condemnation of the accused. Although the announcement of an indictment, for example, will necessarily have severe consequences for the accused, a prosecutor can, and should, avoid comments which have no legitimate law enforcement purpose and have a substantial likelihood of increasing public opprobrium of the accused. Nothing in this Comment is intended to restrict the statements which a prosecutor may make which comply with Rule 3.6(b) or 3.6(c).
 Like other lawyers, prosecutors are subject to Rules 5.1 and 5.3, which relate to responsibilities regarding lawyers and nonlawyers who work for or are associated with the lawyer's office. Paragraph (f) reminds the prosecutor of the importance of these obligations in connection with the unique dangers of improper extrajudicial statements in a criminal case. In addition, paragraph (f) requires a prosecutor to exercise reasonable care to prevent persons assisting or associated with the prosecutor from making improper extrajudicial statements, even when such persons are not under the direct supervision of the prosecutor. Ordinarily, the reasonable care standard will be satisfied if the prosecutor issues the appropriate cautions to law-enforcement personnel and other relevant individuals.
