The problem with rummaging through someone’s drawers is that this is done by people who in that process will inevitably find out much more about your life than binary “has CSAM / does not have CSAM in their possession”. There’s no viable way of limiting scope of such rummaging and there is no way to make individual officers forget what they’ve seen. Apple’s system on the other hand provides such guarantees, so I don’t see how it can be compared to these hypothetical rummaging operations.
