What we want to work with manufacturers on is to figure out how can we accommodate both interests in a sensible way? How can we optimize the privacy, security features of their devices and allow court orders to be complied with?

We all love privacy. We all care about public safety. And none of - at least people that I hang around with, none of us want back doors. We don't want access to devices built-in in some way.

What we do is we combine information collected from any lawful source in a single FBI database so we don't miss a dot when we're conducting investigations in the United States. What we make sure of, though, is nobody gets to see FISA information of any kind unless they've had the appropriate training and have the appropriate oversight.

Our investigation looked at whether there is evidence classified information was improperly stored or transmitted on that personal system, in violation of a federal statute making it a felony to mishandle classified information either intentionally or in a grossly negligent way, or a second statute making it a misdemeanor to knowingly remove classified information from appropriate systems or storage facilities.

There are two things that matter in a criminal investigation of a subject.What did the person do, and when they did that thing, what were they thinking? When you look at the hundred-years-plus of the Justice Department investigation and prosecution of mishandling of classified information, those two questions are obviously present.

In our counterterrorism cases and our counterintelligence cases, we can issue all kinds of - of layers of approval in the FBI, a national security letter to find out the subscriber to a particular telephone number and to find out what numbers that telephone number was in contact with. Not the content of those communications, but just the connection.

I care a lot about privacy. I also care an awful lot about public safety. There continues to be a huge collision between those two things we care about.
