The typical customs role in the past was border-focused; it dealt with our operations at the border. In the immigration business, a lot of the activity that we pursue involves working with people who are either in the immigration system in one of our detention holding centres or who are the subject of an immigrant warrant that we have issued for their arrest because they have not appeared for a hearing or some other activity.
We have teams of approximately 350 officers who work inland on these sorts of things: doing investigations, running down warrants, going out and arresting people who have not appropriately presented themselves for immigration hearings, etc.
