A letter report issued by the Government Accountability Office with an abstract that begins "Globally, alien smuggling generates billions of dollars in illicit revenues annually and poses a threat to the nation's security. Creation of the Department of Homeland Security (DHS) in March 2003 has provided an opportunity to use financial investigative techniques to combat alien smugglers by targeting and seizing their monetary assets. For instance, the composition of DHS's largest investigative component--U.S. Immigration and Customs Enforcement (ICE)--includes the legacy Customs Service, which has extensive experience with money laundering and other financial crimes. Another DHS component, U.S. Customs and Border Protection (CBP) has primary responsibility for interdictions between ports of entry. In summer 2003, ICE announced that it was developing a national strategy for combating alien smuggling. Among other objectives, GAO determined the implementation status of the strategy and investigative results in terms of convictions and seized assets."

Testimony issued by the Government Accountability Office with an abstract that begins "The possibility that terrorists and criminals might exploit border vulnerabilities and enter the United States poses a serious security risk, especially if they were to bring radioactive material or other contraband with them. Although Customs and Border Protection (CBP) has taken steps to secure the 170 ports of entry on the northern and southern U.S. borders, Congress is concerned that unmanned and unmonitored areas between these ports of entry may be vulnerable. In unmanned locations, CBP relies on surveillance cameras, unmanned aerial drones, and other technology to monitor for illegal border activity. In unmonitored locations, CBP does not have this equipment in place and must rely on alert citizens or other information sources to meet its obligation to protect the border. Today's testimony will address what GAO investigators found during a limited security assessment of seven border areas that were unmanned, unmonitored, or both--four at the U.S.-Canada border and three at the U.S.-Mexico border. In three of the four locations on the U.S.-Canada border, investigators carried a duffel bag across the border to simulate the cross-border movement of radioactive materials or other contraband. Safety considerations prevented GAO investigators …
