Which fields are mandatory for a non-unique identifier inquiry in the NCIC?

The correct answer identifies the fields that are essential for conducting a non-unique identifier inquiry in the National Crime Information Center (NCIC). In such inquiries, specific fields must be provided to ensure that the data being queried yields accurate and relevant results.

The inclusion of ORI (Originating Agency Identifier), along with the demographic fields of AGE, SEX, RAC (Race), EYE (Eye color), HAI (Hair color), HGT (Height), and WGT (Weight), is necessary because they collectively help differentiate individuals who may share similar names or identifiers in the system. This comprehensive set of information enhances the ability to narrow down the results effectively, thus facilitating accurate identification.

In essence, the mandatory nature of these fields stems from the necessity to provide as much information as possible to eliminate ambiguity, especially in scenarios where multiple subjects may fit the queried criteria. This is vital in law enforcement operations where precise identification is crucial for the safety and effectiveness of responses.

Other choices do not include all the necessary fields, particularly ORI, which is critical for tracking and validating where the inquiry originates from, and also lack some demographic details that are essential for a full and effective inquiry.
