Its hard to believe that we cannot arrest/execute a terrorist just because of that card... and the result is, thousands of dead innocent civilians and street dancing demons in Palestine.
Within a few days of 9-11, the FBI published a comprehensive timeline on Atta which I'm almost certain included his entry into the USA in 2000. This info must have been the Able info.
At the time, I guestioned "HOW" this info on Atta come to light so quickly. Now I know. They had it all the time.
This gives Berger's bungling burglary a motive: "Get Able out of the FBI/CIA files. Make Able stop at the Pentagon".
