This argument is exaggerated. Sure some potential child kidnappers may be able to get away with their crimes, however they would probably not have evidence of such on their phones had it not been for encryption on Apple's iPhones.
The higher likelyhood of such evidence can be a talking point during interrogation of a suspect as the police can bluff that they have cracked such encryption and/or have figured out a criminals password, and this could potentially get a criminal to "talk"
I'd venture to say that most of these child so-called predators aren't very hardcore in their criminality in that they merely look for the low hanging fruit but are ultimately not very manly in terms of committing real violence (I'm thinking mostly of those that get busted on that one reality show "to catch a predator"). If parents kept a better eye on what their kids are up to, all of this would be a moot point and the NSA would have no leg to stand on here. I know, they'd adopt a new boogyman.The higher likelyhood of such evidence can be a talking point during interrogation of a suspect as the police can bluff that they have cracked such encryption and/or have figured out a criminals password, and this could potentially get a criminal to "talk"
