The FBI Assault on Apple: Was This Necessary?

The FBI created a firestorm over digital privacy by taking Apple to court and demanding access to the iPhone of a terrorist killed in San Bernardino. Now the Bureau says, "Never mind" -- at least for the moment. It turns out that somebody else may have figured a way to break Apple's encryption. That's raising a host of questions. Doesn't the FBI have its own hackers? Is Apple's vaunted security all it's cracked up to be? Should a private company become a surveillance arm of the government in the interests of national security? We hear a variety of answers.
