Feds fire back on San Bernardino iPhone, noting that Apple has accommodated China

As expected, federal prosecutors filed their formal response on Thursday in the ongoing case involving the seized iPhone 5C that was used by one of the shooters in the San Bernardino terrorist attack in December 2015.

Last month, the government obtained an unprecedented court order under the All Writs Act, an obscure 18th-century statute, which would compel Apple to assist in the government's investigation. If the order stands up to legal challenges, Apple would be forced to create a new customized iOS firmware that would remove the passcode lockout on the phone. Apple has said both publicly and in court filings that it will fight the order as much as possible, and the company has drawn support from many cryptographers, tech companies, and even the husband of a survivor of the attack.
