This would be a very challenging job of investigative reporting, and indeed might win a prize for someone who succeeded in proving (to most people's satisfaction) who actually planned the attacks.
Thanks for answering the first question about the 1968 Federal anti-rioting law USC Title 18, Chapter 102 18USC102. The question is How many unduplicated prosecutions and/or investigations have the FBI done using this code. I was told by a lawyer the information maybe available in the Library of Congress or through some data on crime statistics that the FBI keeps.
