So Bush ignored the message "Bin Laden determined to attack", Does it really matter??

61. I think the general idea is that taking the warning seriously might improve response

Perhaps if the WH's hair was on fire about the idea of domestic strikes people might have re-examined protocols, thought harder about what might happen, etc.

We cannot know whether that would have changed anything in practice, but it is not far-fetched to imagine ways it could have.

For instance, a sentry operates under certain rules. When he gets a message, "Based on things we are picking up, we think there might be attempts to infiltrate us tonight," it doesn't change anything he is supposed to do. He has the same rules as always.

But the message does change the way he acts as sentry.

Consider this—a hijacked plane would have been identified as such almost immediately on 9/15. Why? Because everyone had gotten a message from 9/11. The idea of a hijacking was being taken very seriously on 9/15.
