Why this matters
How do you find one man responsible for an attack, when he is hiding across international borders with no fixed address and years to disappear? The FBI's answer was patient, unglamorous work: flight school records, financial trails, intercepted communications, the same tools investigators still use for organized crime today.
What makes this reading uncomfortable is the second half. Investigators had pieces of this plot before September 11. Nobody connected them in time. Students trace both stories at once, the successful hunt and the failure that came before it, and neither one is simple.
From one teacher to another
This is detective work at the largest scale. The FBI didn't just respond on September 11; they built the case against the men who planned it. Students see how investigators think—following money, listening to intercepted calls, connecting names and dates and flight records. It's also a lesson in institutional failure: they were picking up pieces of the plot, but nobody was pulling them together.
