How is cell phone tracking going to prevent another 9/11? And looking at the historical track record, the DoD has done a lot of killing and very little 9/11 prevention in the past 24 years.
The heuristic is that DoD doesn’t do counterterrorism. I don’t expect DoD to prevent terror attacks just like I don’t expect the FBI to blow up bunkers in Iran. We don’t need numbers to be able to confidently estimate that the number of Iranian bunkers blown up by the FBI is approximately zero.
