Um... I think that's the point. The site wasn't "secured."
The site was secured means: The military didn't leave anything behind that could have been used by the enemies. You think for a minute that any officer would have given the orders to leave this compound unattended, knowing that there would be 380 TONS of stockpiled explosives? They didn't find any of that stuff - period end of story. The NBC reporter said that or her lack of reporting that means they didn't find anything.
