Orin Kerr has been writing for the Washington Post about the All Writs Act, the law that the FBI is using to order Apple’s assistance. If you are interested, start with Part One.

From Part Two, this quote:

As I mentioned in my first post, I don’t know which side should win. Part of the reason is that I’m waiting on development of the facts. But as this post has showed, part of the problem is that the scope of authority under the AWA is just very unclear as applied to the Apple case. This case is like a crazy-hard law school exam hypothetical in which a professor gives students an unanswerable problem just to see how they do.

We are definitely exploring unknown territory.
