My domain is about the resources we need to do the diagnosis when there's a problem. That's done and it's done again. It's looked at on a constant basis, and issues are flagged up to base commanders and to security people as they arrive. I'm confident that we have the resources to do that appropriately and to the right level of certainty.
As to the issue of whether we need more fences, more guards, more technology, and more something to help solve that problem, I'm really not in a position to say.
