28 CFR, Part 23

Overview
28 CFR Part 23 is a guideline for law enforcement agencies. It contains implementing standards for operating federally grant-funded multijurisdictional criminal intelligence systems. It specifically provides guidance in five primary areas: submission and entry of criminal intelligence information, security, inquiry, dissemination, and the review-and-purge process.

28 CFR Part 23 does not provide specific, detailed information on how the standards should be implemented by the operating agency but, instead, provides the ability for each agency to develop its own policies and procedures.
