I am uninformed about Able Danger, but is he talking about another Clinton screwup? and others Clinton placed in positions?
Able Danger was a data mining operation run out of DoD using open sources (meaning nothing was confidential and they didn't use government software to gather the information).
Able Danger identified the Atta cell in Brooklyn one year before 9/11, but nothing happened with the information. Lawyers in Clinton's Justice Department and Defense Department shut it down, it's assumed, but there is a major crunch on to keep the guys from testifying.
