The government has already admitted that they brought the cover sheets that were marked “classified” with them to Maralago and placed those with the documents that did not have such cover sheets, before posing them on the floor for the photos they leaked to the press.
It is as if corrupt vice cops carefully documented a drug raid with photos, and then leaked one that help prove the drugs were planted on the defendant. I think that the FBI and Jack Smith were told, in essence, "Don't worry how the case turns out in court, just dirty Trump up enough publicly to take him out of the running for President."
Trump's lawyers are serving up the facts and law so as to permit Judge Canon to make a definitive ruling that wrecks the entire classified documents case and leaves the FBI and the prosecutors publicly discredited. That would make the judicial process serve a name-clearing function that helps an innocent defendant.
