The government’s brief does not acknowledge the sweeping implications of its arguments. It tries to portray its requested unlocking order as narrow and modest, because it “would not require Apple to make any changes to its software or hardware, … [or] to introduce any new ability to access data on its phones. It would simply require Apple to use its existing capability to bypass the passcode on a passcode-locked iOS 7 phone[.]” But that undersells the implications of the legal argument the government is making: that anything a company already can do, it could be compelled to do under the All Writs Act in order to assist law enforcement.
Were that the law, the blow to users’ trust in their encrypted devices, services, and products would be little different than if Apple and other companies were legally required to design backdoors into their encryption mechanisms (an idea the government just can’t seem to drop, its assurances in this brief notwithstanding). Entities around the world won’t buy security software if its makers cannot be trusted not to hand over their users’ secrets to the US government. That’s what makes the encryption in iOS 8 and later versions, which Apple has told the court it “would not have the technical ability” to bypass, so powerful — and so despised by the government: Because no matter how broadly the All Writs Act extends, no court can compel Apple to do the impossible.
