These are the wrong questions to ask. There's no doubt that total surveillance would result in more crimes being solved, and more criminals being successfully prosecuted. It's not a question of whether the technique is effective enough that it should be allowed.
The question is can the government be trusted with a backdoor into our personal devices that "only they" can use? Should the people trust their government to only use that access lawfully, and can the people trust their government to protect that access from unlawful outsider access?
Since we've seen nothing but incontrovertible evidence, throughout history and to this day, that government cannot be trusted with this level of access to our personal devices (lives), then I can only hope that Apple and companies like it will fight to provide us with secure devices, and that our courts will protect our right to strong encryption to protect our personal data.
