Since there seems to be a lot of discussion regarding fingerprints, I thought I would share what I learned through some reading. In 2015 the FBI began keeping a data base that included both criminal and civil fingerprints. Prior to 2015, if someone was fingerprinted for a noncriminal reason, the prints would have been cross-checked with the criminal prints on file & then possibly discarded. However, prints obtained as of 2015 for civil reasons (jobs, background checks, licensing) are now saved in a fbi biometrics data base .
IMO this is what I understand of the process & can be found at the link below:
