Homeland Security became a primary concern of the nation after the terrorist attacks of September 11, 2001. On March 1st, 2003, the Border Patrol along with four other Federal entities merged into Customs and Border Protection, under the Department of Homeland Security. The U.S. Border Patrol continues its efforts to control our nation’s borders. The 21st century promises to provide enormous leaps in technology that can be applied to border enforcement. The modernization of the Patrol advances at an astounding rate as new generations of agents develop innovative ways to integrate the contemporary technology into field operations. New specialized technology is being created within the Border Patrol that holds increasing potential to assist agents in fulfilling the mission of the Patrol. Additional cooperation with neighboring countries increases border safety and law enforcement efforts.
