"We have ways to make some of those cuts. And they involve the intel that comes in, the analysis that goes on. For example, we often times, for travelers entering the United States, we won't not do what is called a secondary inspection just because they are a 35-year- old male who appears to be Muslim, whatever that means. But we know from intelligence that if they have a certain travel pattern over a certain period of time, that should cause us to ask some more significant questions than if we don't."
