Sounds more like it didn't fit into their notion of the problem, so they ignored it. A lot like the reason we didn't connect the dots before, and a lot like what happens so much in our government.
Here's a radical idea. Fire EVERY SINGLE CIVIL SERVANT. Then hire all new staff. You can re-hire the existing people, but the must be put in different departments.
Two years of hell, but after that, thousands of NEW IDEAS from people who don't know "how it is always done".
In my employment, they have a program which rotates people around. It hurts when you lose a good person out of your project, but it brings you new people who have a fresh perspective.
If the cell members lent or borrowed or traded cell phones and or credit cards, the data mining would show a hit for the person with the cell phone or credit card hit, NOT the physical person who may have used it.
Atta's cards or cell phones might have been used (getting hits on Able Danger's radar) with Atta not even in the country.

Why do you think many of the Clinton people took Civil Servant jobs before he left office?
