What we did in this audit was examine certain practices of the agency at the border for preventing illegal entry, and we took samples during a period of time. We did find there were instances where the agency would have had enough information to identify certain people at the border as people of concern, but there were still some people who were able to get through. Our samples were small and the number of people we talked about who got through were small. However, when you look at the size of the number of people who are actually entering, the level of those who were able to get through who shouldn't have gotten through, was high enough in our samples that it is concerning.
