JM 9-21.300
Upon receiving a Witness Security Program application, OEO will arrange for the USMS to interview the prospective witness as part of the application review process. Because of the need for this preliminary interview, it will be necessary for OEO to receive the application for the witness's participation in the Program as soon as it is clear that the individual (1) is an essential witness, (2) is endangered, and (3) will need to enter the Program. This USMS's "Preliminary Interview" is designed to provide the witness with an overview of Program guidelines and the services that the witness can - and cannot - expect to receive. It will also ensure that all parties involved are aware of the issues which need to be resolved prior to Program authorization and relocation.
The USMS will coordinate the preliminary interview directly with the prosecutor or agent. The USMS requires that a copy of the application and threat assessment be provided to it prior to, or at the time of, the scheduled interview. Before providing a copy of the threat assessment, the agent should contact his or her headquarters Witness Security Program contact concerning any special instructions.
