Do you have any evidence that this is happening? You don't think someone would have noticed by now if it were?
And as I pointed out, we're not talking about a search warrant on a person, we're talking about whether it's necessary to get a search warrant to look at a picture to determine if it's an illegal image.
28 billion photos are uploaded every week to Google Photos[1]. That’s at least 280k false positives per week.
Should we really be performing 30 search warrants on innocent people per second?
