FILE - In this Wednesday, Sept. 9, 2015, file photo, Apple CEO Tim Cook discusses the new iPhone 6s and iPhone 6s Plus during the Apple event at the Bill Graham Civic Auditorium in San Francisco. Apple has spent years setting itself up as the champion of individual privacy and security, a decision that’s landed it in the government’s crosshairs over an iPhone allegedly used by one of the San Bernardino shooters. The high-profile case presents risks for Apple almost no matter what it does, and may spill over into the broader tech industry as well, potentially chilling cooperation with federal efforts to curb extremism.
