If anyone knows where he is and thinks someone else will turn him in, they might think, 'Hey, it might as well be me that collects the reward money.' So turning in bin Laden can become a corrosive, self-fulfilling prophecy.

It's very psychologically destabilizing. They [al Qaeda detainees] were likely told that they would be abused and/or killed by the U.S., described to them as the great Satan. So then, when they are treated pretty well, that is likely to be alarming.

Bin Laden has to be more nervous.

I don't see how he can elude capture forever. .... The lighter he travels, the less likely he is to be detected. Yet he also needs protection, and the more defended he is, the more he is a hard target to destroy and is easier to find.

You build up a store of information which allows you to piece the information together. Part of what you do is compare what you learn with what you're getting from other sources.
