If I am leaking somebody's medical records, I'd leave those items in. After all, they are essential to validating the records.
On the other hand, if I'm an ass making stuff up, I'd settle for redaction. If I don't redact, then I have to make up values, which will be quickly exposed as false. On the other hand, if I redact, then the sheeple will nod (such of them as actually look at records, redacted or not, valid or not), having been conditioned by court-ordered or FOIA disclosures.
