The visual derivative is enough to tell the difference between a collection of CSAM and say documents, or pictures of protests.

They have never given details on what this 'visual derivative' actually is. If it's detailed enough to recognise it as CSAM, then Apple isn't allowed to look at it.

Using this mechanism to search for things other than CSAM would be unconstitutional under the 4th amendment. https://www.economist.com/united-states/2021/08/12/a-38-year-old-charity-will-be-integrated-into-apples-newest-operating-system https://www.economist.com/united-states/2021/08/12/a-38-year...
