Land Ports of Entry: CBP Should Update Policies and Enhance Analysis of Inspections, Report to the Committee on Homeland Security and Governmental Affairs, U.S. Senate [open pdf - 4MB]
From the Highlights: "CBP [U.S. Customs and Border Protection], within the Department of Homeland Security (DHS), is the lead federal agency charged with a dual mission of facilitating the flow of legitimate travel and trade at the nation's borders while keeping terrorists and their weapons, criminals and their contraband, and inadmissible aliens out of the country. GAO [Government Accountability Office] was asked to review CBP's process for inspecting passenger vehicles, pedestrians, and commercial vehicles at land POEs [ports of entry] to secure the border. This report examines to what extent CBP (1) has processes and policies for inspections, (2) monitors inspection activities, and (3) has measures to assess its efforts to detect illegal activity of passengers, pedestrians, and commercial vehicles at land POEs. To address these questions, GAO analyzed CBP documents and data related to inbound inspections; interviewed officials; and observed operations at a non-generalizable sample of seven land POEs, selected to reflect a range of traffic volumes and geographic locations, among other things. This is a public version of a sensitive report that GAO issued in June 2019. Information that DHS deemed sensitive has been omitted."
