Exactly this. I've used this on many FOIA cases where the defendant public body has argued for redaction. One was an 800 page manual on jail procedures which the body said was 100% subject to redaction. On the first round we got them to concede the table of contents, after that it wasn't worth arguing further, so sadly we had to file a motion for in camera review and the judge had to take it home and read all 800 pages. The final determination was that only the locations and operations of the keys, how knives were stored in the kitchen, and how the armory operated were actually redactable. Of course, then the public body appeals it and the appellate justices then have to read the 800 pages all over again. But eventually you should get a half-decent result.
