NICS Process for FFLs
28 CFR 25.9 - Retention and destruction of records in the system
§ 25.9 Retention and destruction of records in the system.
(a) The NICS will retain NICS Index records that indicate that receipt of a firearm by the individuals to whom the records pertain would violate Federal or state law. The NICS will retain such records indefinitely, unless they are canceled by the originating agency. In cases where a firearms disability is not permanent, e.g., a disqualifying restraining order, the NICS will automatically purge the pertinent record when it is no longer disqualifying. Unless otherwise removed, records contained in the NCIC and III files that are accessed during a background check will remain in those files in accordance with established policy.
(b) The FBI will maintain an automated NICS Audit Log of all incoming and outgoing transactions that pass through the system.
(1)Contents. The NICS Audit Log will record the following information: Type of transaction (inquiry or response), line number, time, date of inquiry, header, message key, ORI or FFL identifier, and inquiry/response data (including the name and other identifying information about the prospective transferee and the NTN).
(i) NICS denied transaction records obtained or created in the course of the operation of the system will be retained in the Audit Log for 10 years, after which time they will be transferred to an appropriate FBI-maintained electronic database.

Done did, numerous times. E.g., in order to determine whether an FFL is routinely selling guns to persons who are not allowed to purchase guns.Now would you please explain to me what reason you see for any law enforcement officer to refer to the NICS data base when investigating a crime.
