Gone?

Obviously, the identifiers (DNA profiles, fingerprints, modern biometrics like facial shape and retina layout) of past convicted criminals have to be saved.

But what about people that are acquitted? Should they be permanently tracked? Maybe there is a lower bar for this that the prosecutor can jump over even when they fail to convict?

What about people who just need a background check for one reason or another? Do teachers, child care workers, folks applying for security clearance, etc really belong in a database whose purpose is to track criminals?

Should every identifying characteristic searched end up added to the database if it's not there already?
