Which of the following is not an acceptable entry for the REASON field when running a III?

The correct choice is a random identifier, as it does not provide meaningful context or linkage to a legitimate law enforcement reason for accessing the criminal history information. The REASON field is designed to capture specific information that justifies the request for accessing a person's criminal history. Acceptable entries should be relevant and pertinent to the law enforcement purpose.

In contrast, an agency case number, a criminal warrant, and a pending investigation all serve as appropriate entries. They indicate a clear and traceable law enforcement purpose, which is essential in maintaining the integrity and accountability of law enforcement operations when accessing sensitive information in the Interstate Identification Index (III). These entries support the necessity of obtaining criminal history records and ensure that requests are filed under legitimate circumstances as outlined by legal requirements and agency protocols.
