Which typically will be a court case, or at least questioning by police. This can be quite a destructive event on someone's life. Also, there's no mechanism for whitelisting outlined in the paper, nor can I imagine a mechanism that would work (i.e. now you've got a way to distribute CP by abusing the whitelisting fingerprint mechanism or you only match exact cryptographic hashes which is an expensive CPU operation & doesn't scale as every whitelisted image would have to be in there).
Also, your entire premise is predicated on careful and fair review by authorities. At scale, I've not seen this actually play out. Instead either the police will be underworked & not investigate legitimate cases (too many false positives) or they'll aggressively police all cases to avoid missing any.
