I think the biggest challenge our office has is responding to questions about what we're doing, because so much of it is confidential. One of the biggest challenges is satisfying people that we really are investigating what we ought to be investigating; that we're doing a good job and working hard.
There are a lot of people who like to criticize, but the fact is these are people's lives we're dealing with. They should be kept confidential where they ought to be kept confidential. In due course, reports will come out and what we have to say will be said. We're not a kangaroo court. We do these things carefully and deliberately, and hope we do a good job. But that's the biggest challenge.
