Now I understand your not that good at critical thinking as you voted for the incompetent one twice but let me clue you in on how it's done.
When the second plane hit maybe someone like you could even realize we were being attacked. At that moment according to the VP SS burst into his office and took him to the bunker below the WH. So what did the Secret Service do for Dubya? They let him look stupid for over seven minutes (which come to think of it we let him look stupid for 8 years) before he left those children. Those children who were being expose to danger the longer he stayed there. All those children in the whole school were being exposed while he was contemplating his navel. So do everyone a favor and for once think before you look to much like dubya.
