So you're saying that I craft a file that has the same hash as a CSAM one, I give it to you, you upload it to google, but it also happens to be CSAM, and I've somehow framed you?
My point is that a hash (granted, I'm assuming that we're talking about a cryptographic hash function, which is not clear) is much closer to "This is the file" than someone actually looking at it, and that it's definitely more proof of them having that sort of content than any other type of evidence.
I don't understand. If you contend that it's even better evidence than actually having the file and looking at it, how is not reasonable to then need a judge to issue a warrant to look at it? Are you saying it would be more reasonable to skip that part and go directly to arrest?
