When a target is not called to testify pursuant to JM 9-11.150, and does not request to testify on his or her own motion (see JM 9-11.152), the prosecutor, in appropriate cases, is encouraged to notify such person a reasonable time before seeking an indictment in order to afford him or her an opportunity to testify before the grand jury, subject to the conditions set forth in JM 9-11.152. Notification would not be appropriate in routine clear cases or when such action might jeopardize the investigation or prosecution because of the likelihood of flight, destruction or fabrication of evidence, endangerment of other witnesses, undue delay or otherwise would be inconsistent with the ends of justice.
