A recent repot by the Government Accounting Office, Or GAO, the Department of Homeland Security, which oversees the Border Patrol, is implementing new security measures that may leave significant areas less secure than before...

the House Homeland Security Committee

 chaired by Rep. Peter King (R) NY requested information from the GAO from testimony and reports from the Customs and Border Protection (essentially the Border Patrol Arm of the Department of Homeland Security) as to how much of the border is secure and how well.  According to the GAO report,  of the 2,000 miles of border approximately,  873 miles were considered to be operationally controlled. Of those 873 miles, 15 percent were considered "controlled"  85 percent managed.  Border Patrol officials believe with the newer technologies being implemented there will be fewer requests for resources such as officers and actual patrols.  However, many of the new technologies have not worked, such as the virtual fence, which has all but been scrapped after it didn't work as promised, or equipment that malfunctioned within weeks of going into operation.
