And, then, second, as David said, the screening processes -- clearly, though we've spent billions and billions of dollars, there's simply not enough equipment to find the things that need to be found.
KRUGMAN: I think we do want -- I mean, someone's head ought to roll over this. Something needs to be looked at. But if you read your military history, every major military surprise that ever happened, there were ample warnings. You go back to the record; you find out there was information.
The trouble is, there is so much information. You know, there's 500,000 people on this list we're talking about. Stuff is going to fall through the cracks. Ultimately, you do what you can, but someone who is prepared to die while killing a bunch of civilians, that's going to happen now and then. In fact, we're quite lucky it didn't happen now.
But, you know, I think -- I think we are using a lot of 20/20 hindsight. What was the kind of thing that always happens whenever anything goes wrong.
DOWD: Well, to me, OK, so the situation now is, what do we do in the aftermath of this?
So what it looks like we usually do is we profile an article of clothing, not the person.
And so we're reluctant, because of politically correctness, to profile a person, but the shoe bomber happens and now we all have to put our shoes on the conveyer belt for it to go through, and we're not going to profile a person.
This guy's underwear is on fire...
I'm afraid what we next have to profile...
(UNKNOWN): Everyone's going to have to wear their underwear on the outside.
BROOKS: They're talking about -- TSA's now talking about new rules for international flights. For the last hour, you can't have any personal items in your lap. You can't get up for the last hour of a flight on international flights. So this is going to affect us in the same way.
But, you know, one of the other interesting things about this, Ruth, is that this man, apparently, according to the information we have now, and it's early. You point out a lot of the early information turns out to be wrong.
But, apparently, he spent time in Yemen and was trained by Al Qaida in the Arabian peninsula, which -- and this is an increasing -- I don't want to say that this is necessarily a new front in the war on terror, but this is coming up over and over. There was a U.S. Yemen air strike on Thursday morning.
MARCUS: I think you could say it's a new front in the war on terror. It's not particularly surprising. And it doesn't mean that Afghanistan isn't a concern and the areas in Pakistan aren't a concern. But it does underscore the new reality that terror is -- you know, it's a, sort of, floating crap game. And you can move to it different locations. And if you have a failed or failing state, as Yemen is, as Somalia is, things can -- those are breeding grounds and areas where Al Qaida in the Arabian peninsula is flourishing.
BROOKS: Let's not materialize it. It's an ideological thing. I mean, this guy, as I said, fit the classic profile. He's rich. He's trapped between two worlds, the traditional world of his imagined past and the modern world of being a mechanical engineer.
