Border Patrol: Key Elements of New Strategic Plan Not Yet in Place to Inform Border Security Status and Resource Needs, Report to Congressional Requesters [open pdf - 7MB]
"Within DHS [Department of Homeland Security], U.S. Customs and Border Protection's (CBP) Border Patrol has primary responsibility for securing the border between ports of entry, and reported that with its 18,500 agents it apprehended over 327,000 illegal entrants at the southwest border in fiscal year 2011. Across Border Patrol's nine southwest border sectors, most apprehensions occurred in the Tucson sector in Arizona. GAO [Government Accountability Office] was asked to review how Border Patrol manages resources at the southwest border. This report examines (1) apprehension and other data Border Patrol collects to inform changes in border security for the southwest border and the Tucson sector, in particular; (2) how the Tucson sector compares with other sectors in scheduling agent deployment and to what extent data show that deployments have been effective; and (3) the extent to which Border Patrol has identified mechanisms to assess resource needs under its new strategic plan. GAO analyzed DHS documents and data from fiscal years 2006 to 2011, and interviewed officials in headquarters and five southwest border sectors selected based on cross-border illegal activity, among other things. Results cannot be generalized across the southwest border, but provided insights into Border Patrol operations."
