The truth needed about 911

I just listened to Reprsentative Wheldon talk about military intelligence that used open sourcing to research about the people that was involved in the 9-11. What I do not understand that this situation was known prior to the 9-11 problem. I remember reading about it for years. I really believe the Bush Administration knew it was coming and let it happen. (If you remember supposedly Reagan used the hostage situation against Carter and supposedly had an agreement to release the prisoners after he was elected ) Is there anyway to get the truth out of Washington. The people that are elected maybe need to go to jail if they do not tell the truth. Yet Bush gave the ex head of the CIA a freedom medal for his service to this country. If the CIA lied then maybe he should have gone to Jail. There is slowly truth coming out but nobody is going to jail. (I remember the head of CIA covered up for Reagan on the Central American affair.) I realize we elect these people but in their polilical campaigns tell us thing that are almost untruths. Are the American People got so ignorant that we do not know what is going on?Where is the press ? Is our media so controll by big corporations that they are not allowed to tell the truth? Do we elect people that do not represent us - but seem to represent big corporations. What can be done about this situation? I guess anybody can ask questions like I am doing but years ago where I was taking a course and the questions written was more inportant than writing the answers. Getting long winded- We need some changes in this country bad.
