SURVEILLANCE, PRIVACY and TECHNOLOGY

New York judge rules in Apple’s favor. A federal judge ruled against the Justice Department yesterday, over whether the tech giant can be compelled to extract data from a locked cell phone. The decision could affect the fight between Apple and the FBI over the phone of one of the San Bernardino shooters. [Wall Street Journal’s Devlin Barrett]  Magistrate Judge James Orenstein said that the 1789 All Writs Act did not authorize him to force Apple to act, reports Ellen Nakashima. [Washington Post]

Apple v. FBI. Apple and the FBI will present their cases before a congressional panel today concerning a court order demanding that the tech giant provide the federal agency with data from the San Bernardino shooter’s iPhone.

LIBYA

US military involvement will be needed in Libya to defeat Islamic State, even if a unity government is formed, Army Brigadier General Donald Bolduc, commander of US special operations forces in Africa, has said.

HILLARY CLINTON EMAIL CONTROVERSY

The last of the 30,000 emails on Hillary Clinton’s private server were released yesterday, including an email dated July 3, 2009, concerning North Korea, which prompted the original referral to the FBI last year for a review of Clinton’s handling of classified information. [New York Times’ Steven Lee Myers and Julie Hirschfeld Davis]  Nick Gass provides a compilation of the “23 must-read emails from Clinton’s inbox.” [Politico]

Meanwhile, Attorney General Loretta Lynch has fielded further questions about potential criminal charges in relation to Clinton’s handling of classified emails, stating that the Department of Justice will not obey “any kind of artificial deadline” and will look to “follow the facts, follow the law and come to an independent conclusion.” [The Hill’s Jesse Byrnes]

The US’ system of classifying documents is “dysfunctional, arbitrary and counterproductive,” says Abbe David Lowell, the Hillary Clinton email affair being the latest demonstration of this. Clinton is “right” to argue that government information is “overclassified” and “poorly labeled.” A “saner” system of classification is needed. [New York Times]

AFGHANISTAN

More US troops than planned may remain in Afghanistan at the end of the year to support national security forces.

[The Hill’s Kristina Wong]
