Apple CEO Tim Cook said his company will not comply with a federal court order demanding that it unlock an iPhone of the San Bernardino terrorist attackers. Cook says he will appeal the order, and take the legal fight all the way to the Supreme Court if needed.

If the case does go all the way to the Supreme Court, it could define privacy for a generation. "60 minutes" talked about this issue with FBI Director James Comey in October 2014, and Apple CEO Tim Cook in December 2015.

Cook argued that most people keep personal information on their phones, and they should be able to protect that data. He said that is done through encryption, and creating a work around would be problematic.

"If you put a back door in, then that back door is for everybody. For good guys and bad guys," Cook told Charlie Rose.

Comey told Scott Pelley that he is also committed to protecting the privacy of every day Americans, but he is concerned about criminals being able to escape the law.

"The notion that we would market devices that would allow someone to place themselves beyond the law troubles me a lot," Comey said.
