A system of cameras and censors are used along the border and interior to help detect the movement of illegal immigrants crossing through the dense brush.

Our border patrol does a great job under these very dangerous conditions. They use very sophisticated equipment, including gamma rays, to detect drugs and illegal immigrants as they enter the U.S.

The technology used to detect if vehicles are carrying radioactive material is so sensitive it can tell if a person recently received radiation as part of a medical procedure.

Since September 11, the U.S. has significantly improved its security to prevent another attack.

Illegal immigration is crisis for our country. It is an open door for drugs, criminals, and potential terrorists to enter our country. It is straining our economy, adding costs to our judicial, healthcare, and education systems.

We must safely secure our border by investing in more law enforcement and technology, and receiving cooperation from the Mexican government.

Our enemy is motivated by hatred and will not stop planning more plots against until they are ultimately defeated. Today was an important and necessary victory in the war, but there is a long road ahead. We must remain committed if we are to succeed and protect our liberty.
