Thank you for the question.
I'll start the answer off, and then my colleague can round it out.
This is the single most important issue that we have, certainly from the police, and I know that I speak for my colleague when we talk about how we're going forward to deal with encryption, and going dark, and managing things on the Internet. It is, as I said, the single greatest impediment to our effective investigations as we proceed with managing the terrorist threat.
