What does the CIA do for US citizens directly?

What the CIA does for U.S. citizens is to protect us. I feel so grateful every single day that we have not been attacked, because it would be so easy to bring a nuclear device in, or to bring in a major bomb. It's so easy to do that, and yet we keep uncovering these plots and we keep rolling up the terrorists who might start plotting. In other words, we roll them up before the point of starting to plot. That's why I personally feel so grateful to these people, because they work night and day without any credit. All they get is criticism in the press and from politicians, and yet they are saving our lives.
