Befuddling that this happened again. It’s not the first time

- Paul Manafort court filing (U.S., 2019) Manafort’s lawyers filed a PDF where the “redacted” parts were basically black highlighting/boxes over live text. Reporters could recover the hidden text (e.g., via copy/paste).

- TSA “Standard Operating Procedures” manual (U.S., 2009) A publicly posted TSA screening document used black rectangles that did not remove the underlying text; the concealed content could be extracted. This led to extensive discussion and an Inspector General review.

- UK Ministry of Defence submarine security document (UK, 2011) A MoD report had “redacted” sections that could be revealed by copying/pasting the “blacked out” text—because the text was still present, just visually obscured.

- Apple v. Samsung ruling (U.S., 2011) A federal judge’s opinion attempted to redact passages, but the content was still recoverable due to the way the PDF was formatted; copying text out revealed the “redacted” parts.

- Associated Press + Facebook valuation estimate in court transcript (U.S., 2009) The AP reported it could read “redacted” portions of a court transcript by cut-and-paste (classic overlay-style failure). Secondary coverage notes the mechanism explicitly.

A broader “history of failures” compilation (multiple orgs / years) The PDF Association collected multiple incidents (including several above) and describes the common failure mode: black shapes drawn over text without deleting/sanitizing the underlying content. https://pdfa.org/wp-content/uploads/2020/06/High-Security-PD...

I want to believe this is malicious compliance.

Not to mention when the White House published Obama's birth certificate as a PDF. I remember being able to open it and turn the different layers off and on.

What happens in a court case when this occurs? Does the receiving party get to review and use the redacted information (assuming it’s not gagged by other means) or do they have to immediately report the error and clean room it?

Edit: after reading up on this it looks like attorneys have strict ethical standards to not use the information (for what little that may be worth), but the Associated Press was a third party who unredacted public court documents in a separate Facebook case.

This has happened so many times I feel like the DoJ must have some sort of standardised redaction pipeline to prevent it by now. Assuming they do, why wasn't it used?

"There are major differences between the Trump 1.0 and 2.0 administrations. In the Trump 1.0 administration, many of the most important officials were very competent men. One example would be then-Attorney General William Barr. Barr is contemptible, yes, but smart AF. When Barr’s DOJ released a redacted version of the Mueller Report, they printed the whole thing, made their redactions with actual ink, and then re-scanned every page to generate a new PDF with absolutely no digital trace of the original PDF file. There are ways to properly redact a PDF digitally, but going analog is foolproof.

The Trump 2.0 administration, in contrast, is staffed top to bottom with fools."

Follow the letter of the law, but not the spirit.

Given the context and the baldly political direction behind the redactions, it's not at all unlikely that this is the result of deliberate sabotage or malicious compliance. Bondi isn't blacking these things out herself, she's ordering people to do it who aren't true believers. Purges take time (and often blood). She's stuck with the staff trained under previous administrations.

The covid origins Slack messages discovery material (Anderson & Holmes) were famously poorly redacted pdfs, allowing their unredacting by Gilles Demaneuf, benefiting all of us.
