It sounds like building #7 was the tipping point for many of you. I know it was for me as well. Same with the FBI having the previous terrorist suspect in their custody (Boston Bombing) and not keeping tabs on him after letting him go. Russian Intel I am certain rarely works with the US government, so when they extended them an olive branch they should have grabbed it tightly.
I believe that 9/11 was much like Pearl Harbor in the sense that the red flags were flying spectacularly before hand, but the attacks were allowed to proceed in order to accomplish certain objectives. Many of which I believe they (The Federal Government) have met or exceeded.
The reason I go back to the Pearl Harbor attack is the parallels between then and 9/11. In the instance of Pearl Harbor the justification to let the attack proceed was twofold. 1 was to get the US people up in arms over a foreign enemy attack (nearly all states lost men, so the pain inflicted was universal), and 2 was not to let the Japanese Government know that the US Signal Intelligence Corp had broken their code.
Keeping information such as this hidden for eternity is incredibly difficult, as a small minority of Americans generally do not tend to let these things rest if things smell fishy. Now that the vast majority of WW2 vets and their family members are dying off in significant numbers, do not be shocked to see more data regarding these events begin to appear in the public sphere.
History always repeats itself, and if the American People can be conned once then surely they can be conned again. Think for a moment that if those in power during the attack on Pearl Harbor KNEW that this attack was imminent and let it proceed; then does anyone think that there would be any limitations on what the US government would do to incite war. Please remember folks that it was not only dragging the US into war, but also forcing the American People to surrender many of their God Given rights for the cause, much like what we are seeing now.
I doubt that Clapper will ever loose one day of his pension let alone viewing the world from behind bars for lying to the American People under oath. The NSA spying on the American People does need to stop, and one hell of a lot persons who know they are violating US Citizens Rights to privacy need to be brought before a jury of their peers.
