Prosecutors in the ongoing encryption feud between Apple and the FBI have filed a new motion to compel Apple to unlock an iPhone used by one of the San Bernardino shooters. In the government's filing, as reported by The Verge, the government has fired back against the public arguments Apple has made against providing assistance. From The Verge:

"The government and the community need to know what is on the terrorist's phone, and the government needs Apple's assistance to find out," the filing argues. " Apple's rhetoric is not only false, but also corrosive of the very institutions that are best able to safeguard our liberty and our rights."

In particular, the government's filing takes issue with Apple's argument that assisting in this one case will endanger the security of iPhones for millions:

"There is no reason to think that the code Apple writes in compliance with the Order will ever leave Apple's possession. Nothing in the Order requires Apple to provide that code to the government or to explain to the government how it works," the filing argues. "Far from being a master key, the software simply disarms a booby trap affixed to one door."

The feud between Apple and the FBI has only continued to escalate over the past month as those on both sides of the issue have continued to make their cases to the public. Those arguments will move to the court room relatively soon, however, as both sides will get to make their case before a judge on March 22.

Update: CNBC reports that Apple legal head Bruce Sewell responded to the filing by calling the Department of Justice "desperate" and saying it had "thrown all decorum to the wind."

"The tone of the brief reads like an indictment," he said.

Sewell called the brief an "unsupported, unsubstantiated effort to vilify Apple."
