The Greatest Horror.

If you haven't been watching Glenn Beck's series "The Perfect Day" on MSNBC, then you MUST watch the final segment tonight. (7 and 9pm Eastern on CNN) "The Perfect Day" is what papers and tapes that have been found in Iraq and Pakistan, show what a "perfect day" would be to terrorize Americans. What is the perfect day? Remember Beslan? That's it. And there is some unnerving evidence that they are looking at our schools.

I copied a lot of Tuesday night's transcript here, but it's important to read the whole thing. As I listened I felt this deep down fear. God help us if this were to happen.

Glenn Beck has been discussing this with Brad Thor, author of a series of fiction books on terrorism, but his research revealed a reality that is chilling:

THOR: Well, we talked about things. First of all, we based it on this Al-Qaeda model of being like a shark, how they swim big concentric circles. They don't come right in and bite you. They collect Intel, getting closer and closer, tighter and tighter in the circles. But before they attack, before they take the bite, they come up and they bump you. They want to see are you a threat, are you going to put up a fight, or can we get you. And that's what we're seeing across the country with the two Saudi Arabian men. I talked to people in that investigation down in Florida, in the Tampa area, the two Saudi men that boarded that school bus and wouldn't get off and all that kind of stuff where there was a strong feeling among people involved in that investigation that that was a dry run. We see this, we see school buses missing, 17 in Texas. We see thousands of school bus radios missing in the Northwest, the Pacific Northwest. We find, in the course of this investigation, I talked with -- it would blow your mind how many law enforcement departments I talked to that have interrupted active surveillance on schools across the country. The dots are there.

GLENN: So tonight -- first of all let me just tell this story again. In Iraq we found a diskette that had a -- that had downloaded all of the Department of Education security measures, and they're all available online.

THOR: Okay. What was found in an insurgent, an Al-Qaeda affiliated safehouse over in Iraq, they were school blueprints, basically, floor plans for schools across the country. San Diego, California, West Salem, Oregon, Boyertown, Pennsylvania, schools in Texas, Virginia, New Jersey, and this was very, very disconcerting and there was a cover story that was concocted that, hey, this was just some Iraqis who were involved with the Ministry of Education in Iraq and they're looking to rebuild their schools and all that kind of BS.

GLENN: Unbelievable. I mean, who would buy that, that they come to us to look at the architectural plans of schools all around the country, six or eight -- I mean, were these remarkable schools, architecturally speaking, Brad?

THOR: No, no, it wasn't incredible Frank Lloyd Wright but it shows you how desperate the FBI is to get to the -- they are desperate. They are working so hard to prevent this from happening. That's one thing I want your listeners to know is that they do not want this to happen. They are working hard, but at the same time they are trying to prevent people from panicking.

THOR: Exactly. In one of the things that we're seeing here is that they are looking for the softest targets possible, and that means when you're looking at schools in the heartland, you look at how long it takes from a 911 phone call to getting a tactical team, not just patrol officers but a tactical team on site, and in a lot of places that takes a long time, especially if you have a multijurisdictional swat team. So what these terrorists are looking for from the stuff that's been recovered, and tonight on your CNN Headline News program, we're going to have John Giduck on who wrote the book terror at Beslan who wrote the book, the dress rehearsal. Bin Laden has said what we did in Russia, we will visit 100 times worse in America. He's even gotten a religious edict allowing him to kill up to two million American children and what they are looking for is a school where the girls are old enough to rape and the boys are too small to fight back.

GLENN: I want to go back to Pakistan because there was something else that we touched on last night and we didn't play this tape. We were only cleared to play a few seconds of it. I'm going to try to expand that and put it on tomorrow's newsletter so you can see it. There's eight hours of tape that we found in Pakistan in another Al-Qaeda training camp, eight hours of tape where they made a mock American school. The guy, the terrorists came in and they took mock American students, they took one little boy and they shot him in the head immediately and then in English said, "Now follow our directions exactly." It's how to take over an American school. It's eight hours of tape. Only an hour of it has been seen by American law enforcement officials here in America. We've only seen part of it. What else is on this eight, the eight hours? What is this?

THOR: It's kind of the master planning tapes of Al-Qaeda. It is the full library as best as our intelligence and military people know, and what they did was they edited down to a one-hour version to show American law enforcement in particular what they need to be prepared for, and the most chilling thing, there's the drive-up motorcycle assassinations and things like that but the one thing that's resonated throughout the law enforcement community has been the attack on the school where they have the mock role players. They've even got -- you can hear in the background there's almost like a soundtrack of children crying, to add realism to the training of these Al-Qaeda operatives, and they are issuing their commands in English and then what they're doing almost kind of PR media savvy is they take a bunch of them up to the roof and they execute them on the roof, kind of for the television cameras to show how serious they are. And one of the -- if that isn't frightening enough, Glenn, what we've discovered is all of their plans on how to surveil the schools, how to get in the schools, how to hold the schools, the one thing that's missing from all these plans, there is no exit strategy. These people are not planning to leave alive. They want to play this out for the media. They want to absolutely devastate us emotionally, psychologically and also financially with this kind of attack here.

I'm wondering and asking you what you think our Government and our people's reaction would be to such a scenario? Not what you think we should do, but what you think would happen in the aftermath of terrorists killing our children in their schools.
