The Border Patrol could quickly cut a significant portion of our resident illegal alien population if they were allowed to operate in the nation's interior. They know where many of the illegal aliens live, but aren't able to do anything about it due to being tied to the border itself. ICE/HSI currently has the mandate for interior enforcement, but doesn't have sufficient manpower or will to engage in serious interior enforcement efforts. Many Border Patrol Sectors could easily increase their apprehensions ten-fold if they were turned loose. This would result in a huge reduction in costs associated with the large illegal alien population in the U.S.
