Decision Model for U.S.-Mexico Border Security Measures: President Trump's Proposed Border Wall, History of Security Infrastructure by ICE, CBP, DHS, Intelligence Community, Law Enforcement

This late 2017 report has been professionally converted for accurate flowing-text e-book format reproduction.

The Department of Homeland Security (DHS) has invested billions of dollars to prevent illegal drugs, immigration, weapons, and currency from transiting across the U.S.-Mexico border. DHS has not created a sufficient standardized method to measure whether an investment in a security measure is cost-effective when combining assets. To take it one step further, DHS has not created a model that combines cost-effectiveness of a security asset while simultaneously determining how it will contribute to achieving operational control of the border.
This study provides an in-depth look into the current risk-based model DHS uses, the administrative and physical infrastructure of U.S.-Mexico border security, and a critical view of DHS' annual budget. A decision model is presented that will give policymakers a process to choose a combination of border security investments that will achieve operational control of the border while remaining within budgeting constraints. A lot of work needs to be done for DHS to determine the correct security assets to be placed at the U.S.-Mexico Border to maintain operational control and cost-effectiveness. This study does not determine which security assets need to be put into place, but it provides a decision process that will be an asset for policymakers to save federal time and money assigned to border security investments.
