Nope. First the dashes may not be there. It could also be just the last 4 of the SSN (which is still bad). Also other info could be present that is not easy

Nope. First the dashes may not be there. It could also be just the last 4 of the SSN (which is still bad). Also other info could be present that is not easy to identify as private. For example, say the cop was caught using extreme racial slurs against a man who was being arrested after giving his child an STD via rape. It would be extremely difficult to redact enough so that you do not release any info that could identify the victim. Even as a person who knows a thing or two about looking stuff up on the internet it would be hard to redact just enough to protect the identity of the victim while not redacting too much about the police misconduct. Doing so automatically would be a strong AI sort of problem.
