An Apple iPhone 6s Plus smartphone is displayed Friday, Sept. 25, 2015 at the Apple store at The Grove in Los Angeles.  On Wednesday, Feb. 17, 2016, a federal judge ordered Apple Inc. to help the FBI hack into an encrypted iPhone used by Syed Farook, who along with his wife, Tashfeen Malik, killed 14 people in December in the worst terror attack on U.S. soil since Sept. 11, 2001.  Apple has helped the government before in this and previous cases, but this time Apple CEO Tim Cook said no and Apple is appealing the order. (AP Photo/Ringo H.W. Chiu)
