What must support all entries into the IDACS/NCIC Wanted Person files?

The requirement for written documentation such as reports and warrants to support all entries into the IDACS/NCIC Wanted Person files ensures that there is a formal and verifiable basis for the entries made into these critical databases. This protocol helps maintain the integrity and reliability of the information shared among law enforcement agencies.

Incorporating written documentation, like arrest warrants or detailed incident reports, provides a clear legal foundation for the inclusion of an individual in the Wanted Person files. This is crucial for operational effectiveness, as it assures that the data can be substantiated in case of inquiries or legal challenges. Moreover, it aligns with the procedural strictures necessary for maintaining national standards in criminal justice systems, enhancing accountability, and preserving due process rights.

The other options suggest more informal or insufficient forms of support, which do not align with the standards required for maintaining such important law enforcement databases. Therefore, written documentation is integral to ensuring that the information in the Wanted Person files is accurate, legally justified, and easily verifiable.
