The lesson is the importance of never becoming untethered to oversight and accountability.

The promise I've tried to honor my entire career, that the rule of law and the design of the founders, right, the oversight of courts and the oversight of Congress will be at the heart of what the FBI does.

Privacy is tremendously important. I believe the American people, and all people, should be skeptical of government power, should ask hard questions: What is the authority? What is the oversight? That's the way it ought to be.

Cybercrime is becoming everything in crime. Again, because people have connected their entire lives to the Internet, that's where those who want to steal money or hurt kids or defraud go. So it's an epidemic for reasons that make sense.

We can only query against that which we have collected. And so if someone has never made a ripple in the pond in Syria in a way that would get their identity or their interest reflected in our database, we can query our database until the cows come home, but there will be nothing show up because we have no record of them.

The important thing is to get oversight in there fast, and make it highly visible.
