I think we need to find out why the Able Danger information was destroyed in 2000.
we also need to find out why it was destroyed by the Pentagon in 2004, well after serious investigations had begun. In my opinion, this is very similar to Arthur Andersen destroying documents that might be needed for a pending investigation, but much, much worse because it involves critical questions of national security.
The program was destroyed in 2004.
One possibility (and this is why, yes, we need to know about why they ended the program) is that with info coming out to Rep. Weldon and being told to the 9-11 commission, maybe the intelligence community thought it best to disband AbleDanger, maybe to continue it under another name or in another department?
