I came in with a healthy skepticism about these programs. My team evaluated them. We scrubbed them thoroughly. We actually expanded some of the oversight, increased some of the safeguards. But my assessment, and my team's assessment was that they help us prevent terrorist attacks. In the abstract, you can complain about 'Big Brother' and how this is a potential program run amok. But when you actually look at the details, then, I think we've struck the right balance.
