of 2006 authorizes the construction of 700 additional miles (1,100 km) of the double chain link and barbed wire fences with light and infrared camera poles.
On October 26, 2006, U.S. President George W. Bush signed the Secure Fence Act of 2006 (Pub.L. 109–367) into law stating, “This bill will help protect the American people. This bill will make our borders more secure. It is an important step toward immigration reform."[1]
The bill was introduced on September 13, 2006 by Congressman Peter T. King, Republican of New York. In the House of Representatives, the Fence Act passed 283–138 on September 14, 2006.[2] On September 29, 2006 – the Fence Act passed in the Senate 80–19.
Background[edit]
The fencing built under the 2006 act was not the first border fencing in the United States. The U.S. Border Patrol first began to erect physical barriers in its San Diego sector in 1990.[3] Fourteen miles of fencing were erected along the border of San Diego, California and Tijuana, Mexico.[4]
Provisions[edit]
In 2006, at the time it was passed, George W. Bush's White House touted the fence as "an important step toward immigration reform."[1] The White House Office of the Press Secretary stated that the Act "Authorizes the construction of hundreds of miles of additional fencing along our Southern border; Authorizes more vehicle barriers, checkpoints, and lighting to help prevent people from entering our country illegally; Authorizes the Department of Homeland Security to increase the use of advanced technology like cameras, satellites, and unmanned aerial vehicles to reinforce our infrastructure at the border."[
