Prior Policies

  • GAO found challenges for the National Guard and for active-duty military forces in providing support to law enforcement missions. DOD officials cited restraints on the direct use of active duty forces, operating under Title 10 of the United States Code in domestic civilian law enforcement, set out in the Posse Comitatus Act of 1878. Federal officials stated a number of broad issues and concerns regarding any additional DOD assistance in securing the southwest border. DOD officials expressed concerns about the absence of a comprehensive strategy for southwest border security and the resulting challenges to identify and plan a DOD role. DHS officials expressed concerns that DOD's border assistance is ad hoc in that DOD has other operational requirements. Further, Department of State and DOD officials expressed concerns about the perception of a militarized U.S. border with Mexico.
