Thank you so much.
I've taken a note from my good friend René's use of his iPad for timing, so hopefully I'll get it on, although certainly not with the same expediency as my friend Mr. Housefather in the way he was able to deliver questions.
We're well into this. One of the things that typically happen with expert testimony is that they are given time to situate themselves within their subject matter expertise. In your opening remarks, you didn't have an opportunity to do that. I want to give you that opportunity now. I understand, from your profile, that you publish widely on issues of privacy, surveillance and communications. Perhaps, as an opportunity to provide context to that, you can share what expertise you're here with today.
