 Basically, they have a top person to go to a walkthrough. Then they take a look at diagrams. Then they look at the magnetometers, where they are. They see where the counter-sniper team locations are set up. And then they sometimes go through the entire area again. So I think what happened in this particular situation, based on what I've been told, is there were supposed to be some other folks helping with some things, and somehow something fell through the cracks. Back to you.
