 Let's get back out to our national security expert. This is John Guandolo. John, as a former federal agent, I got to ask you, is it normal? I got a couple pictures I'm going to put up on the screen for the folks watching the live video stream. The first one is the FBI hosing down the roof. I believe this is the day after the shooting. Seems kind of weird, John. Here's another one. You know, it's odd when the roof is too steep for snipers, but it is safe enough for a water hose and the cleansing of evidence.
