The first phase of Gatekeeper focused on the 5 5/8 westernmost miles of the border, extending from the Pacific Ocean to the San Ysidro Port of Entry near San Diego.5 U.S. migration routes immediately shifted eastward, and the use of professional human smugglers known as coyotes or polleros increased. In May 1995, the Border Patrol initiated Operation Disruption to target human smugglers, and also established new checkpoints on interior highways.
Phase two, although not formally part of Gatekeeper, was launched in October 1995. It consisted of the appointment of Alan Bersin as the Attorney General's Special Representative on Southwest Border Issues and the establishment of the first immigration court at the actual boundary, inside the San Ysidro Port of Entry. The court expedited hearings and subsequent deportations of undocumented immigrants apprehended attempting to enter the U.S. with false documents or through false representation.
Phase two also introduced IDENT, an automated biometric identification system, to facilitate identification of repeat offenders and "criminal aliens", i.e., illegal immigrants with criminal records or active warrants for their arrest. The Border Patrol also intensified relations with local law enforcement agencies to counter the flow of migrants through the Otay Mountains.6

Academic Noam Chomsky has said that Operation Gatekeeper was a "militarization of the U.S.-Mexican border" and alleges it was because North American Free Trade Agreement would have increased illegal immigration into the United States; therefore, Gatekeeper was a precaution to stop future illegal immigration.7
