Not going to happen for a variety of legitimate reasons. For one the FBI has databases that might do that, but only if the persons are suspects. In the case of AQ they had databases at the CIA for that, but only for foreigners. Those databases are now at NCTC where they have both foreign and domestic individuals but only if the domestic are suspects.
What you seem to advocate is an all-powerful government prior to 9/11 while obviously realizing that would an incredibly bad idea with this administration. There are two unrealistic assumptions you are making: 1. the government has everyone in a database and 2. the database actually can sort out the bad guys from the good guys without false positives. The first assumption may be true, we don't really know anymore, especially in the current admin. The second will never be true. What will happen instead is false positives like what you see in the movie Brazil.
Do you assume that Fast and Furious never happened because it would have to be a government conspiracy?
A decent question, but that operation left significant real world evidence that it took place. That evidence was mostly suppressed until our agent Brian Terry was killed. The suppression of the evidence and the operation itself was a govt conspiracy until the evidence was revealed. Now all parties acknowledge it took place although there is disagreement on the details. So there is no longer a conspiracy of silence but still somewhat of a conspiracy or collusion between the media and the perps to try to keep it out of public discussion.
Palmer, if you can look at all this stuff (including a law enforcement criminal investigation of the forgery of Obama’s birth certificate and draft registration - and confirmation that the media was threatened by Soros’ crew), and still think there is no real-world evidence of a problem/conspiracy, I don’t know what more I can do for you. I could talk your toes off about all the crimes and ethics breaches committed by the Hawaii government and Passport Office, but what would be the use, if you won’t even believe law enforcement?
BTW, the “Gorelick wall” between FBI, military, and CIA was NOT a factor in Able Danger’s work, because the AQ cell that was pinpointed by that military intel consisted of FOREIGNERS, not US citizens. US Rep Curt Weldon as well as Sen Arlen Specter were working to get answers as to why the leads were not pursued when there was no legal roadblock to doing so, when the DOD put a gag order on the members of Able Danger. And then the media machine went after Weldon to get him beaten in an election before he could push for any more answers.
