Probably easier to slip a "naughty" image that doesn't contain a minor into the image database. An image that resides in a target's iCloud storage. Or soon will. Then it would take a super high level human reviewer to determine that original image, although sexual in nature, is not in fact illegal. There are so many parties that can submit images to this database, it presumably wouldn't be too hard to subvert one of them with cash or laziness.
