good question, the company responsible for the security at the world trade center was called Securacom, and a principal in that company was marvin bush, president bush's younger bro. i believe that company was also responsible for the security at dulles airport that day as well. speaking of al qaeda, dont forget where they got their fertilizer from, it was the cia, who continued to water their roots up til 9/11. and of bin laden, why was it that in the days after 9/11 when all airport traffic was grounded, his family (brother, cousins, etc) was gathered up and allowed to fly out of the country? that one is strange too.
