In Fiscal Year (FY) 2018, 396,579 aliens were apprehended between POEs on the southwest border. Thus far this fiscal year, more than 100,000 aliens have been apprehended between POEs along the southwest border. In addition, we have seen a stark increase in the number of family units apprehended between our POEs on the southwest border. Combined with the recent arrival of the Central American caravans—which have combined into one of unprecedented size— the flows of illegal entries between ports of entry demonstrate significant challenges in securing our border. Our border security efforts have three primary components: personnel, technology, and infrastructure.
Infrastructure Tactical infrastructure, including physical barriers and complementary capabilities, has long been a critical component of CBP’s multi-layered and risk-based approach to securing our southern border.
Between Ports of Entry The land along the border between the United States and Mexico is extremely diverse, consisting of desert landscape, mountainous terrain, and urban areas.
Today, we have several types of barriers, including steel bollard and levee wall, along nearly one-third, or 654 miles, of the Southern border. The recently passed Consolidated Appropriations Act of 2018 supports CBP’s mission through investments in border infrastructure and related technology,
to include $1.4 billion for the largest investment in border wall in more than a decade. We are eagerly putting this funding to work to improve our nation’s security, and encourage Congress to continue to support investments in the high-priority border wall system.
If you read fully they need more towers and infrastructure to help find illegals at long range.......and they need better facilities at POE's to handle the numbers coming across...............said they were not set up properly for post 9/11 needs......
