U.S. Customs and Border Protection (CBP) currently claims extraordinary authority to stop and question people at interior immigration checkponts in the 100-mile border zone, which runs along our southern border with Mexico, our northern border with Canada, and our maritime boundaries on the Pacific and Atlantic oceans. If you find yourself at an interior immigration checkpoint, know that you have rights. Although CBP likes to act like its authority is unlimited, it is not. Understanding what Border Patrol agents can and cannot do will help you to better protect yourself.
