Which process is not performed on the gang file?

The process of hit confirmation is not performed on the gang file. Hit confirmation typically involves verifying whether a person or item associated with a NCIC (National Crime Information Center) entry matches a specific request, often based on a warrant or alert. This process is more commonly associated with criminal history inquiries or stolen property rather than specialized databases like the gang file.

The gang file serves a different purpose, primarily focusing on documenting gang members and relevant gang activity. Background checks relate to a review of an individual’s criminal history or affiliations, which could involve checking against the gang file, but this is a separate function. Data entry is also part of maintaining the gang file, as it involves adding records about gang affiliations, members, and incidents. Lastly, file purging is necessary to maintain the integrity and relevancy of the data, ensuring outdated or inaccurate information is removed, and is a recognized process for both the gang file and other NCIC files. Thus, hit confirmation does not apply to the gang file, distinguishing it from the other processes that are relevant to the file's operation.
