Homeland Security: Challenges Facing the Department of Homeland Security in Balancing its Border Security and Trade Facilitation Missions, Statement of Richard M. Stana, Testimony before the Subcommittee on Infrastructure and Border Security, Select Committee on Homeland Security, House of Representatives [open pdf - 205KB]
Richard M. Stana discusses "the longstanding challenge of balancing our nation's security and commercial needs, an issue that is especially important in the aftermath of the September 11, 2001, terrorist attacks that changed the nation's security environment. Addressing this challenge now falls principally to the Department of Homeland Security (DHS) and its Border and Transportation Security directorate. Within this directorate, the responsibility has been assigned primarily to the Bureau of Customs and Border Protection (BCBP). BCBP consists of the inspections component of the former U.S. Customs Service; the Border Patrol and Inspections components of the former Immigration and Naturalization Service (INS); and a former component of the U.S. Department of Agriculture, the Animal and Plant Health Inspection Service (APHIS)."
