keep it as long as you want, but you don't want to, and the reason why is that the parisians and the belgians are not going to have it for that long. i think you can keep this pace up for a couple weeks and then i think in the end, by 90 days, it's got to start to tailor down. i think people are going to start to ease up also. psychologically, we're coming into the holidays. what will happen, i believe, is they'll start getting more comfortable with the presence of armed security and soldiers. what i think the europeans are going to get good at and they're going to have to, in any of these countries where they start hunting for these terrorists or are conducting operations, we're going to see a more plain clothes security apparatus. you can't spot the undercover police officer, which gives them the element of surprise if there's a terror attack because they can respond and nobody knows who they are, and two, you don't visually see the weapon, you don't see that highly trained, armed police officer.
