The reason for the increase is because we have a lot more agents out there. We have 2,400 agents, and we're making it a lot more difficult [to enter]. We're frustrating their efforts because we have a constant presence along the borders.

That does not mean the Tucson Sector is going to send any yet.

We need the permanent checkpoints - they send a message of deterrence.
